Bug ID: 495375
Summary: mpv idle inhibition doesn't work with dmabuf-wayland
Classification: Plasma
Product: Powerdevil
Version: 6.2.2
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

Target Milestone: ---
SUMMARY
Using the dmabuf-wayland vo with mpv doesn't inhibit KDE's screensaver from
activating.
mpv appears to do the right thing, powerdevil/kwin not handling subsurfaces
properly is suspected, see mpv issue:
https://github.com/mpv-player/mpv/issues/15181
STEPS TO REPRODUCE
1. set the screensaver|screen blanking delay to a low value
2. run mpv --no-config --vo=dmabuf-wayland --stop-screensaver=yes|always <file>
OBSERVED RESULT
Screensaver/Screen blanking turns on, even while the video is playing
(--stop-screensaver=default|yes) or paused (--stop-screensaver=always)
EXPECTED RESULT
powerdevil should recognize mpv playing and inhibiting the screen blanking.
