I builded from source of 4.10.2 release from github. Often when I run UE4Editor I experience UI glitch with popups on mouse over event (sometimes I do not experience this behavior. In that case everything run quite smoothly).
Hardware spec info: (download htm file and open it in browser)
Video demonstrating the glitch: https://youtu.be/92Ou-Nsc6Jc
I’m not sure where a problem is.
Default Editor settings are set.
Xubuntu 14.04 x64 (using GTK), using 4.2.0.27 kernel
UPDATE
I forgot to mention important fact that I use i3wm
instead of xfwm
. But note that I haven’t had any issues like that (applications like Blender, Gimp etc… run always without a problem) until I installed UE4Editor.
Do you have any hints, please?
