The linux client has intense screen tearing and visual artifacting when looking with the mouse in big picture mode.
The joysticks all work fine, it’s just when using any more of mouse input. I’m wagering it’s something related to gamescope as it’s mostly fine when in desktop mode barring some screen tearing which is more likely related to vsync being off when I checked it, but I haven’t ran it in gamescope on desktop yet as I don’t feel like relearning the gamescope arguments rn. It occurs more when vsync is on and the difference between the games frame rate and the streams frame rate widens, but under BPM it will still occur under all combinations of settings I tried (different resolutions, h265/264, 8 bit/10 bit, upscale mode). The issue doesn’t seem to occur on the unofficial client gf infinity so it seems like a bug specific to the official client.
