Public bug reported: I'm having a strange issue with the game Path of Exile (free). With Ubuntu Wayland session, vsync on, I get very irregular frame rates, it jumps around 40 fps. If I switch to Plasma Wayland the game is very smooth 60 fps.
I'm running the game from Steam with Proton. I've tried Proton Experimental and Proton 8.0 so far, no difference. The game uses Vulkan so I guess it's being allowed to set up all the swap and presentation stuff pretty much itself... ? MUTTER_DEBUG_DISABLE_TRIPLE_BUFFERING=1 doesn't help Mutter so it's not strictly related to triple buffering, which makes sense since it's a full screen game anyway.
