Hello My system is Asus G75VW Gentoo ~amd64 nvidia gtx660m When Unreal Engine 4.11 is running i get terrible artifacts on all kde5 versions (kde4 was better) like don't updating panel, screen slow updates, black restangles 1-2 second when i close window, screen tearing, etc Please hear to me and may be fix it. Thank you! Unreal Engine works fine!
I found when i change renderer to opengl 3 or 2 artefacts is gone But this is don't useful
But every time when unreal open new window artifacts back
I'm not a Gentoo dev but a fellow KDE user that never saw such problems. The information you posted so far here is not enough for someone trying to understand the problem / reproduce it. First, Unreal Engine is, well..., an engine. What application based on it do you run? Do you run it fullscreen and ALT+TAB out of it or in a window? Also, the output of the following commands would be useful: emerge --info kwin glxinfo
emerge --info kwin | wgetpaste Your paste can be seen here: https://paste.pound-python.org/show/a0a6PxTYWiyPFavRZdU4/ glxinfo | wgetpaste Your paste can be seen here: https://paste.pound-python.org/show/LvWIGGv66x8h0p0ymfZj/ I use Unreal Editor 4.11 in window mode

Try adding a window rule (right click title bar → more actions → special behavior for this application) and then on the "appearance & fixes" tab do "block compositing" → "enforce" → "No"
i think the problem is in plasmashell
Not a packaging issue. Please report upstream.
