Hey there, thanks for the discussion, it's helped me find a way around this problem.
I also use an R-Go split keyboard. I had the input lag issue OS-wide on Elementary OS and Pop OS. The issue disappears on Wayland. After switching to Regolith, which uses gnome-flashback, the issue is no longer there. There is one big exception, though: there's still the same problem on Firefox! All other apps are doing just fine. I wonder whether I can somehow overcome the problem on Firefox as well. I'm no longer sure whether it's a problem in the interaction between Firefox and Xorg or it's a Firefox-specific problem. ** Bug watch added: Mozilla Bugzilla #1640535 https://bugzilla.mozilla.org/show_bug.cgi?id=1640535 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1777708 Title: Desktop briefly becomes unresponsive when typing on 2 keyboards at the same time To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1777708/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
