The README mentions xwayland so maybe it could be in the future

What are the things specifically that work better? because most of the case people dont have issues because of the x11 (the protocol), but because of how the xorg server works

XRender isn't part of the core protocol so it should be implemented in the future. There is already some xrender code in there. Almost no applications use x11 core protocol font, except for cursor. Since the x11 core protocol font (on xorg server at least) is rendered without anti aliasing and doesn't really support unicode.

You dont need it, it's just one way to install it. You can just download the appimage and use that as well. The point was to say that @aizk comment was ridiculous

It should work yes. Fedora by default disables hardware accelerated video encoding but if you use flatpak versions of software (in this case the flatpak version of gpu screen recorder) then it should work. Even 12 year old gpus work.

Lower framerate doesn't really decrease video size because of how videos work, but you can set bitrate quality for the recorded video to reduce the video quality a bit to decrease the size.

What? The link says that you can install it from flathub (https://flathub.org/en/apps/com.dec05eba.gpu_screen_recorder) so you just have to click install and then record. Since its in flathub its also available in many distros "app store"
