[Ubuntu 23.10] Increased responsiveness possibly by setting xwayland-allow-grabs to true in dconf?

Hello,

Recently there was this annoying ‘feature’ that would, for example, search the desktop for “t” if I tried to open the terminal with “ctr+alt+t” (the same for any other shortcut as soon as there’s useable input). I started searching around for a fix until I eventually found org/gnome/mutter/wayland/xwayland-allow-grabs in dconf which, after enabling it, stopped my computer from searching for the letter t on my desktop and opening new tabs everywhere else. It also seems to have had an unexpected upside of increasing responsiveness on my desktop. I.e. much faster word search in .pdf files, snappier opening/closing of windows, seemingly smoother gameplay, etc.

My previous attempts were also to force gdm3 to use xorg (which I edited back because it made things slower), a whole bunch of logging in and out, disabling (and re-enabling) the dock, and a few system restarts. None of these seemed to effect any change though, I only realized better responsiveness after setting allow-grabs to true.

Can someone tell me if my mushy, sleep deprived brain is correct in assuming that this dconf setting made my computer a bit faster, or was it something else?

Thanks!
