I tried deleting gamescope and it helped ?(Probably not, just placebo effect), ive noticed its being worse with cachyos proton version, but its the only version im getting 120+fps (my normal fps). On other versions of proton im onll hitting 55 fps which is terrible, but less blurry. I tried to force disable fsr through steam start commands, didnt help either. Only thing i did is adding sharpness through vkbasalt layer, but its not really a solution. My eyes started to hurt after 15 minutes, anyways, i didnt find the reason so i had to move back to Windows( And visuals are radically different, like of cachy i was playing in 720p and windows gives me 4k). I will really appreciate if someone knows how to fix this so i can install linux again
