Description
For me, text in games were blurry when set to fullscreen and I've been using full-screen borderless to resolve that.
But one game had an issue with that option (part of the window was off-screen) and I found that disabling full-screen optimization allowed for using the fullscreen option without text getting blurry (by right-clicking the exe, going to the Compatibility tab, and checking "Disable fullscreen optimizations").
But enabling that for every game would be tedious and I found regedit changes to enable it globally (from https://www.reddit.com/r/insurgency/comments/ck1429/psa_windows_10_1903_will_now_ignore_the_disable/):

Just wanted to share that discovery in hopes that it helps others using Steam Deck and Windows 11.
Feel free to close this issue and please take this as just a suggestion.
