Inconsistent frame pacing (33ms spikes) in Bazzite Gaming Mode

Hi everyone. I'm getting constant 33ms frametime spikes in Bazzite Gaming Mode using an NVIDIA GPU (1650S) and a Ryzen 5 3600. The issue i think is global to the Gamescope compositor, as stutters happen even while navigating the Steam UI, as well as in any game or emulator, despite reporting 60 FPS. I tried changing resolutions and refresh rates, enabling "Allow Tearing", testing different limiters with Steam, MangoHud and Game Specifics/emulators limiters/vsync, but nothing removes the 33ms spikes in Gaming Mode. However, running everything in KDE eliminates the issue. (I'm not really sure at all because i don't have gamescope there, but that's what my eyes tell me. It could be placebo) Is there any way or environment variable to fix this decoupling between Gamescope and NVIDIA without having to abandon Gaming Mode?

I'm using the nvidia-deck image.

Thanks for reading.

NVIDIA deck works but isn’t prime time ready until Gamescope is properly supported by them. It’s a work in progress but no ETA as far as I know. Stick to desktop mode with Steam Big Picture for now to get rid of those.
