Description Aleksey Samoilov 2016-12-09 16:48:11 UTC

Overview: After launch SDL-version PPSSPP (Sony PSP) emulator, Kwin compositing falls and restart after exit from PPSSPP-SDL. Version PPSSPP - 1.3.0, but Git-builds has same effect.

Steps to Reproduce: just install and run PPSSPP-SDL from official site, or PPA, or compile it yourself.

Additional Information: my system: CPU: Intel Core i3-550; RAM: 8G; Graphics card: Nvidia GTX 760 2G; Nvidia driver: 375.20; OS: KDE Neon 5.8.4.

Sorry I don't understand what you mean with "Kwin compositing falls and restart after exit from PPSSPP-SDL"

Comment 2 Aleksey Samoilov 2016-12-09 17:23:46 UTC

Sorry for my english. I mean, after launch PPSSPP-SDL, compositing disabled (just like after pressing Shift+Alt+F12). After closing PPSSPP-SDL - compositing enabled.

Comment 3 Martin Flöser 2016-12-09 17:27:04 UTC

That's not a bug, but a feature.

The application provides a hint to the compositor that compositing should be disabled. KWin honors that request and stops compositing. With 5.8 the Compositor options provide a setting to disable this behavior.

Hm, yes, you're right. This is not a bug.
