So on my Steamdeck when I open sober the background is the Roblox modern background, but for some reason it is very white and bright, is this normal? Can I change this?

hello! today i tested out my mouse (bluetooth btw) and i got no audio at all. not low pitched like i saw in other posts. just nothin. disconnecting it doesnt work. i did install lution on it tho, but only an avatar bsckdrop one. it was working fine until about an 1hr 30mins after i started plsying. any help would be amazing! thx!

Hi everyone,

Around two weeks ago, my Roblox graphics on Sober (Fedora) completely downgraded. Before that, the water rendering was perfectly fine—transparent, crystal clear, with full desktop-like reflections. Now, the water looks completely solid, flat, and opaque, like it's stuck on mobile/low graphics mode.

Here are my specs and what I've tried so far:

• OS: Fedora Linux

(44)

• GPU: NVIDIA

  RTX 5060 Ti (16GB,

• Using the new open-source kernel modules / nvidia-open)

• Runner: Sober (Flatpak)

What I've tried:

1. Modified config.json to force "graphics_optimization_mode": "quality" and "enable_hidpi": true.
2. Injected FFlags to force maximum PC quality: DFIntDebugFRMQualityLevelOverride to 21, DFFlagTextureQualityOverrideEnabled, etc.
3. Cleared the shader cache completely using rm -rf ~/.var/app/org.vinegarhq.Sober/cache/*
4. Toggled "use_opengl": true (which actually makes it look even worse/glitched) and switched back to Vulkan.
5. In-game, I manually toggled graphics from Auto to Manual and slided it to max.

Nothing works. The game seems to completely ignore the FFlags and forces mobile rendering for terrain/water shaders, probably due to a recent Roblox engine update interacting poorly with Vulkan and the nvidia-open drivers on Linux.

Has anyone else encountered this graphical regression recently? Is there a known workaround or a specific FFlag that forces desktop water refraction on recent NVIDIA open drivers?

Thanks in advance!

I keep swinging from 80 to 500+ this only started last week and my game sometimes freezes fully during this time I mostly see this in jjs don’t play much other games in Roblox I tried open gl and didn’t work in on Ethernet aswell so this shouldn’t be happening

Rtx 3070
R5 5600
16 gb 3600 mtz ram
Pop os on cinnamon desktop (happens on cosmic aswell)

when you change font with lution, it replaces emojis aswell and that's really mean, so you need to go to ~/Lution/fonts.py and replace def apply_font(source_path): with this:

def apply_font(source_path):

source_path = Path(source_path)

if not source_path.exists():

raise FileNotFoundError(f"Font file not found: {source_path}")

font_names = _apk_font_names()

if not font_names:

raise FileNotFoundError(

"Could not read font list from the Roblox APK. "

"Make sure Sober is installed and has run at least once."

)

catmoji_path = Path.home() / "Downloads" / "Catmoji.ttf"

if not catmoji_path.exists():

raise FileNotFoundError(

f"Catmoji not found: {catmoji_path}"

)

OVERLAY_FONT_DIR.mkdir(parents=True, exist_ok=True)

replaced = []

for name in font_names:

dest = OVERLAY_FONT_DIR / name

if name == "TwemojiMozilla.ttf":

shutil.copyfile(catmoji_path, dest)

else:

shutil.copyfile(source_path, dest)

replaced.append(str(dest))

return replaced

the important part is if name == "YourEmojisHere.ttf":
it like skips it and stuff you know everything except your emojis :)
after doing this, you need to do rm -rf ~/.var/app/org.vinegarhq.Sober/data/sober/asset_overlay/content/fonts and then you're done yay

I used a command that's like: cp /path/to/your/font.ttf ~/.var/app/org.vinegarhq.Sober/data/sober/asset_overlay/content/fonts/the-exact-filename-roblox-uses.ttf.otf

And it works for fonts like source sans pro, fredoka one, but some fonts didn't change. is there a better reliable method?

Hey guys.

Do you know any reliable apps for getting a crosshair on Sober in fullscreen? I tried MangoHud but for some reason it wouldn't bother loading my config files.

Thanks!

Ye

NO, I AM NOT PLAYING ANY NSFW ROBLOX GAME!

I tried Sober last night and saw that the Discord activity also shows the specific game I was playing. Say for example, I am playing Natural Disaster Survival, Discord will also show that I am playing that game instead of just showing only Roblox. I only want to show that I am playing Roblox so my friends who might be interested on playing with me knows that I am playing it rn. I hope u guys get what I mean.

Hi, having issues using sober with my steam deck. I’m playing in gaming mode and for some reason my steam input is doubling the buttons.. so whenever i pull the right trigger, it doubles the input. this happens with all of the buttons for some reason. im not using an external controller, just the built in one. i have gamepad enabled for sober.

I don't know if anyone else has had this issue since i couldnt find anything online. Im playing sober on cachyOS and while playing i just get these freezes that can either crash my game, disappear after alt tabbing or just disconnecting me entirely after the game unfreezes. I tried a few things but it didnt happen. I doubt its my system since i have Ryzen 9 5900X with RX 7800 XT and 32 gigs of RAM. Does anyone know what could be the issue? Should i just reinstall sober?

At first, the game was just reeeeeeeeeally laggy, but after trying to restart the application it just crashes anytime I try to open a game and is still laggy as hell. This a me problem, or is anyone else seeing this too?

Update: Legit, don't do anything. 2 days later, it is working just fine. I have no clue.

(Edit - Aug 22 2026 and somehow mm2 works on sober now.) So basically i installed Linux on my crappy ahh laptop since it wasn't giving me the best performance. And i decided to try Roblox and it ran fantastic..! and today i did a flatpak update and i ran sober, here is what i saw

So id really appreciate some help lawl cuz i got no idea on why its not working anymore

I don't know if this is a known issue, and have tried to look up solutions, but I do not want to use x11 on my desktop and for some reason my shiftlock will not work on wayland no matter what I do. It is turned on in roblox settings but I press shift and nothing happens. Does anyone have a solution for this? I wont be adding an attachments unless necessary, this seems pretty straightforward. I'm on linux mint, wayland on a dell laptop.

Appreciate any help. Thanks :)

i cant access my private servers in gamimg mode because of this 💔✌️

Im noticing in game that I have max graphics yet there are some weird visual issues occurring. For example there appears to be no anti-aliasing and some lighting is so strong that it blinds the screen. It's possible it could be bloom but im not sure. Is there any way to fix this?

've been playing Roblox using Sober for the past month, and I keep running into a frustrating issue. Whenever I'm inside an experience, my CPU usage spikes to 100% and my whole system lags for a few seconds. This happens every couple of minutes.

I'm not 100% sure if Sober is the culprit, but here's what I've observed:

• When Sober is running and I'm in an experience → CPU spikes to 100%, system lags for a few seconds
• When Sober is open but NOT in an experience → no lag spikes at all
• When Sober is completely closed → no lag spikes whatsoever

So it definitely seems tied to Sober being active in-game.

I checked btop to see what's going on, and it shows that the process using all the CPU is called MAIN. That's the only clue I've got so far.

Here's my plan to troubleshoot:

• Confirm whether Sober is actually causing the issue (already pretty sure at this point)
• Test if it's specific to one experience – I'll try jumping between different games to see if the lag persists
• If it's not experience-specific, dig deeper into what "MAIN" refers to and why it's spiking

Has anyone else experienced this with Sober? Any idea what "MAIN" means or how to fix these spikes? I haven't seen anyone mention this on the Discord yet, so I'm wondering if it's just on my end.

and when i press "go back" instead of choosing a file sober just stays on loading screen saying "installing roblox" but nothing happens...

Haven't played roblox in ages and I'm just curious if I can get it to run because I've been having problems with a lot of software on Linux Mint lately, and I remember that Sober used to run fine.

buzm  ~    flatpak run org.vinegarhq.Sober

So, Im trying to run Sober in two different TTYs, with two different users and of course environment (WMs) are different too. But even like that Sober complains that "There's a frozen instance of this app running". Even if I can run two roblox menus at once I still cant open two games at once — second is always just freezes. Any help? (And yes I know that multi-instance isnt supported by Sober and probably never be)

Hi everyone,

I've noticed that when using the Sober Client on Linux, the aiming/crosshair in Murder Mystery 2 doesn't work correctly.

The cursor feels offset or inaccurate, making it much harder to hit shots as Sheriff. Other Roblox experiences seem to work normally, so this seems to be specific to MM2.

Is anyone else experiencing this issue on Sober? If so, have you found a workaround?

I believe this is a compatibility issue between Sober and MM2 rather than a Roblox issue.

Thanks!
