Bug ID: 311067
Severity: minor
URL: https://bugs.freedesktop.org/show_bug.cgi?id=45674
Version: 4.9
Priority: NOR
Assignee: unassigned-bugs at kde.org
Summary: video playback shutters (is jerky?!) when enabling
destop effects
Classification: Unclassified
OS: Linux
Reporter: bbutscheidt at yahoo.de
Hardware: Unlisted Binaries
Status: UNCONFIRMED
Component: general
Product: kde
When I enable "System Settings // Desktop Effects // General // Enable desktop
dffects on startup" every video playback (e.g xine with vdpau or vlc not using
vdpau) suffers from the same problem:
the picture doesn't move smoothly, at least every one or two seconds the
picture seems to stop for a nearly not noticeable moment and then quickly jumps
over the lost frames to the current one.
The audio doesn't seem to be affected.
I can find hints like the one in the URL box in www that other people notice
this too - but nothing here so I just want to drop a notice.
On my machine, this problem came with KDE 4 and the introduction of desktop
effects in general, so I had them deactivated. Just gave it a try with new
4.9.3, but the problem is still there.
By the way: looking at a cpu-Monitor the CPU seems to be at ease.
Reproducible: Always
Steps to Reproduce:
1. Enable OpenGL (Desktop Effects)
2. Play a video with xine/ vlc (x-driver seems to be of no relevance) -
Actual Results:
playback shutters/ shivers/ shortly hangs
Expected Results:
Playback should look like when OpenGL (Desktop Effects) are disabled
I am using nvidia-drivers - but I don't know if this is of relevance here
