This is a weird one for me. Fresh bazzite user, have reinstalled bazzite twice.
If I navigate the steam big picture ui with my keyboard or with my gamepad, the colors are fairly consistent and expected but as soon as the mouse is activated and the cursor shows up, the colors become slightly washed out and faded. If I switch back to gamepad/keyboard, the colors revert.
It seems like activating the mouse cursor changes my color profile somehow.
I'm shooting in the dark on troubleshooting, I've tried restarting, reinstalling, changing resolution and disabling HDR. I'm sure this is probably easy and my main failure is not knowing what to search for.
