Bug ID: 368222
Summary: KDE hangs when VLC or dragon plays video
Product: kwin
Version: 5.6.5
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: daniel.armbrust.l...@gmail.com
Much like some of the details in https://bugs.kde.org/show_bug.cgi?id=338999, I
can consistently make the entire KDE desktop hang, simply by playing a video in
VLC, or the Dragon Video player - currently running 5.6.5 of plasma, 5.23.0 of
kde frameworks.
I'm using the NVidia binary driver at version 367.35.
I'm currently using the OpenGL 2.0 rendring backend, with the GLX interface -
have tried OpenGL 3.1 - doesn't seem to make any difference.
I have stable hardware - I was running the 14.04 LTS edition (with whatever
version of KDE is included) for a long period of time with no issues.
After making the (mistake) to upgrade to 16.04 LTS, KDE is nearly unusable on a
multi-monitor system. I'm aware of https://bugs.kde.org/show_bug.cgi?id=346961
and hoping that the claimed fixes in 5.8 finally fix that mess (but still
waiting for a way to easily get 5.8 onto this ubuntu system - doesn't seem to
be any packages for ubuntu yet...)
This issue, is that anytime I open VLC 2.2.2, upon playing a video for a while
- the entire KDE desktop will hang. The hang can be made to happen sooner by
jumping around in the video - it happens within seconds.
The only recovery is to Ctrl+Alt F key to another terminal (and even that
usually takes 30+ seconds to respond) and then kill -9 VLC.
Dragon player seems to behave even worse - launching that player typically
causes my desktop to instantly forget that it has 3 monitors - reconfiguring
itself in a mode where all 3 of my monitors are set to mirror, and their
resolution is set to a very low value.
The Totem video player seems to work ok - so it would seem to be tied to
whatever technique VLC and Dragon have in common for handling video.
Happy to provide any useful debug info, or other information, as I can
reproduce the problem at will.
Reproducible: Always
Steps to Reproduce:
1.Launch VLC - leave windowed.
2. Jump forward and back in the video.
3. Sometimes the video just freezes in VLC. Most times, the entire KDE desktop
hangs - can't even move the mouse.
