Video screen tearing in Ubuntu

Post by 3x5 » Sat Nov 17, 2018 12:05 pm

Hi there, I'm running XnView 0.92, and it's working great, except that I'm getting screen tearing when I play videos inside the program.

I'm running compiz with openGL, and I can confirm that vlc and gthumb both playback video without tearing. Any ideas? Thanks.

Other problems that seem to be related to video:
  • Videos don't always load thumbnails. Sometimes half the videos in a directory won't have thumbnails, even if they're all the same format.
  • Xnview crashes when browsing through videos: Segmentation fault (core dumped)
  • When I play a video, then stop, go back to browsing thumbs, and try to go to a different directory, the application freezes. I'll post some of the cli messages below.

Code: Select all

"(repeat 1)setInSize => calculating aspect ratio from converted input data(1.777778)\nDemux thread stops running...."
"demuxer thread emit finished. repeat: -1/0"
"avplayer emit stopped()"
