so i had this problem before and i fixed it with compatibility settings in properties by disabling fullscreen optimization. But it has arrived again after some days even though that setting was applied ever since. I have tried everything from changing advanced dpi settings, toggling full screen optimization again, refresh, reinstall with completely new profile. restarting windows explorer / my pc, disabling msi afterburner fps overlay, changing some values on about:config suggested on firefox support forum, disabling addons.

I am not sure what to do now, i am using ghost spectre superlite version of windows 10 (custom stripped down iso). I never had this issue before and it only happens with firefox, even fullscreen by f11 works fine, this issue only occurs with fullscreen video i also checked dailymotion.

Originally, there are some modified system files in this specific version but it can be fixed with dism and sfc command though i don't like it brings back some ghost entries which can't be removed. I don't prefer to install stock windows because i feel it's very bloated even for windows 10, let alone 11.

I am wondering if there's an easy solution without doing a clean install or touching anything unnecessarily.
 
you try other browsers ?

libre wolf?

oh, will say I have tried an optimized w10 and had all sorts of issues with games. ive since used ntlite and made my own in 3 pc and runs very nice. check if its not spectre
