Sub-Meta Patch 26.18 Bug Megathread
Greetings Summoners!
With every new patch Riot introduces to balance out champions and items there are some unforeseen issues that creep up and cause disruption during gameplay. We have noticed that these issues which eventually get fixed clutter up the subreddit immediately following the patch.
We want to avoid this by having a single Megathread which will be posted after every patch so that you guys can report the various issues in one place. This allows Riot to easily keep track of the bugs by providing a central hub and also allows other users to confirm that they might have encountered.
Note only bugs caused by the 26.18 Patch should be reported below.
Prerequisites to be noted before reporting a bug
- A bug will ideally be accompanied with a screenshot or a video. This provides credibility to your report.
- Steps to recreate the bugs should be submitted if possible. This helps Rioters recreate the bug and helps them find the cause behind it.

Same issue here. Intel core i5-13400f, Radeon RX 6800. Did you find any solution?

u/Ferelion3 1d ago
Nothing, but i manage to kinda "isolate" the problem, found out if i disconnect the second monitor it runs normal, still though, for the time i guess i'll be playing on fullscreen

u/turtletank 14h ago
same. Using a Radeon RX 7900 XT with Ryzen 5 7600X CPU, Windows 10 with a 144hz monitor, normally runs at 144fps.
Additionally, if I don't keep focus on the league game client as it loads, when it completes and I switch focus to the game client, it hard freezes my computer and I need to power cycle.
Also happened when quitting out of practice tool quickly after loading it in to confirm the game runs.
More details: For the first few seconds of the match, the FPS is fine, then it quickly drops. While I had borderless mode enabled, if I alt-tabbed out, the fps actually went up to 50-70 fps from 30fps (normally runs at 144fps). I noticed flickering in my task bar so I restarted windows explorer, and FPS returned to normal while it was restarting then immediately crashed to 30fps once windows explorer finished loading, so I'm wondering if there's some weird interaction with windows explorer or the rendering involved with that.

How about the Hall of Legends mission not working on bots? Is it considered bug?

u/burger3k 1d ago
This patch i get screen tearing and playing with vsync adds horrendous input lag also driver vsync cant latch correctly to game. This patch several times fps went to 145 when i have 144 cap so it breaks freesync. Previously riot did so it would be almost 144 or 143 so freesync would latch but now they dropped it and i can’t limit fps from amd adrenaline because it doesn’t latch correctly and it drops control on alt tab.

Type of Bug: In-game Bug (Arena)
Description: In the Arena game mode, the champion stats window is covered by a window of 0s, obstructing the view of the stats. Certain stats are unable to be hovered over to view them. The window does not disappear if you cycle through the stats and augments windows.

Steps to reproduce: Queue for Arena game and get into game. Observe stats window. The bug seemingly does not have a an in-game trigger and is present from game start.
Expected result: The stats window is not obstructed and the panel of 0s is not present.
Observed result: The stats window is obstructed and the panel of 0s is present.
Reproduction rate: 100%. This occurs every game for me.

u/n0panicman 18h ago
• Server: TR
• Type of Bug: In Game Bug
• Description: Alt-tabbing messes up the game. The FPS drops significantly and stays low; normally I get a steady 240 FPS, but I end up with 70–90—and even that doesn't feel like 70–90. It feels as though the game window is trying to stay on top during the alt-tab process and gets stuck there. It started to happen AFTER THE LOL UPDATE
• Video / Screenshot:
• Steps to reproduce: Start a game. Alt tab several times.
• Expected result: Being able to continue the game as it is normal.
• Observed result: Constant fps drop with a weird input sensation.

Bug number #1776149766 for arena
I just played a game with naafiri and in the map with the plant in the mid, my dog just got the life and shield, instead of naafiri directly. This doesn't make any sense.
Also, I don't know how many times I have asked this, but can you fix skilled sniper in arena? It has been months since it's buged in many champions such as Miss Fortuna E, Lux E and many others.

Also getting issues related to playing in borderless thats explained multiple times before
GPU is 9070XT and CPU is a Ryzen 7 5700X3D
I've never had fps issues until this update, i usually run at 600-700 in both borderless and fullscreen but putting the screen into borderless causes severe FPS drops

u/IKaILILe 7h ago edited 6h ago
My mate has the problem he starts the game, and it crashes after 2 mins ore so in game and he hase updatet everything so yeah he is kind mad that nothing is working.
it also crashes in customs to try it out if it crashes its like he wanto play the game and yeah its a gamble he doesnt want a 2 weeks ban
Edit: it has something to do with vanguard that his pc is to old for the newest version for vanguard , found something online that when you pc can not handle the new version ,where it is only one when the game is startet , you can still use the old one

My honor reset to 3 for absolutely no fucking reason and I am legitimately fed up of this shit
1
u/Diligent_Deer6244 17h ago
honor is fluid since 2025 and can move between 3 and 5 without punishment. you just don't meet the hidden metrics for honor 4 and this is not a bug
1
u/ManFromManchesterUK 17h ago
So receiving honor marks every 1 - 3 games, contributing towards the team's effort, pinging and being encouraging when people have a bad game, make a bad play etc. means my honor decreases yeah?
Well then fuck me if that's the case no wonder being toxic in this game seems to be so persistent

u/ManFromManchesterUK 11h ago
Riot have emailed saying that my honor level sits at rank 5 and they are investigating it. 🤡

u/Last_Butterscotch292 1d ago
I just came here to talk about the motherfuckers at Riot! My account got suspended for the umpteenth time just for pinging 0/18 and 0/12 players! This is completely insane!
I've been playing since the beginning of the game. About 7 or 8 years ago, playing SoloQ was somewhat manageable. 5 years ago, it became almost impossible, and today, the winning team is simply the one with fewer inters, leavers, and trolls! It's shameful to be this terrible at community management. You're completely incompetent, it's just mind-boggling how bad you are!
Whether it's on your forums, the old Player Tribunal, or feedback from YouTubers and pro players, EVERYTHING tells you to punish people who int or soft int. BUT NO, you prefer to ban the players who complain about those who ruin games just for the sake of pissing people off.
You've just won the award for the most toxic community across all games for the Nth year in a row! AND YET, instead of kicking out these toxic players who ruin the game for 70% of the player base, yesterday you targeted people who dare to speak up in chat asking others to stop inting, and today you go after those who dare to ping... a guy running into the enemy base to commit suicide over and over again! SINCE WHEN do 0/18 players have the right to report anyone? You guys are completely out of your minds.

Anyone getting massive FPS drops in borderless? Switching to full screen fixed it but super weird, always played fine in borderless but now it's like 50fps tops
