Xfce4 and XWayland seem fine. The most notable application showing the slow down is my own application (mrv2), but after a while I can also see the slow down happening on a basic gnome-terminal, where my typing is too fast for the showing of the letters. You can download my application from github at: https://github.com/ggarra13/mrv2/releases/download/v1.1.1/mrv2-v1.1.1-Linux-amd64.deb To reproduce the error: $ dpkg -i mrv2-v1.1.1-Linux-amd64.deb $ mrv2 (Once it opens, press F10) (It will open a Preferences window with a tree on the left, and options on the right). (Switching options in the tree should be immediate, but on my machine, I get a lag of half a second before the options and tree redraw) The problem is intermittent. I can reproduce the issue on my program upon login, but it see the gnome terminal issue after a while of using it.
