Bug ID: 361154
Summary: Running native OpenGL games - with compositing enabled
- breaks Plasma 5.6.0 Window Decorations
Product: kwin
Version: 5.6.0
Platform: Gentoo Packages
URL: http://i116.photobucket.com/albums/o35/bob_mt_wya/KDE%

OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: bob.mt....@gmail.com
Using:
emerge -pv nvidia-drivers xorg-server =sys-kernel/gentoo-sources-4.4.6
[ebuild R #] x11-base/xorg-server-1.18.1-r1:0/1.18.1::bobwya USE="ipv6

[ebuild R ~] sys-kernel/gentoo-sources-4.4.6:4.4.6::gentoo
USE="experimental -build -kdbus -symlink" 85,566 KiB
Including, the following configuration options enabled in my kernel:
CONFIG_DRM_KMS_HELPER=y
CONFIG_DRM_KMS_FB_HELPER=y
Reproducible: Always
Steps to Reproduce:
1. Compositing on
2. Launch a fullscreen 3D/GL based game
Actual Results:
Window Decorations break.
Window shadows become solid black bars around all windows.
Opening new Windows causes alternate monitor (dual-monitor setup) to flicker
rapidly (sync issue / Nvidia driver issue?)
Expected Results:
Window Shadowing should be restored - after exiting the 3D game.
Window Shadows do NOT break if compositing is disabled before running a
GL-based game.
Window Shadowing only restores if I log out (or presumably if I restart
kwin_x11 - I'll test this!!).
Moving or resizing windows has no effect - the shadowing remains in a broken
state. Flicking issues get significantly worse whilst doing this...
Desktop effects (3D Cube, etc.) appear to remain intake and also show the
Window artefacts...
I haven't done much testing - because I only did an update from Plasma 5.5.5 ->
5.6.0 yesterday... I'll add any other useful information as and when... :-)
