When playing video, the video will run a couple of seconds, then randomly turn completely black and stay that way until I move the video player's window. When moving the window the image will alternate rapidly between black and correct. If I stop moving the window when the video is showing, it will remain stable for a couple of seconds and then turn black again.

The video will also turn black consistently when I focus another window.

This is on Linux Mint 17.2 (based on ubuntu trusty).
with kernel: 3.19.0-25-generic #26~14.04.1-Ubuntu
running the xorg-edgers ppa with
xserver-xorg-video-intel 2.99.917.git20150723.a29e765e
Comment 4 Chris Wilson 2015-07-28 20:05:10 UTC
What command do you to play the video? Do you recall if there was a time when everything worked?
Comment 5 Felix Braun 2015-07-28 20:23:47 UTC
I'm using vlc. I'll have to check whether other players show the same problem. I don't have the video problem with the stock trusty driver(2.99.910 ) but  that version has other probmsle
Comment 6 Chris Wilson 2015-07-28 20:27:01 UTC
To be clear, trusty -intel-2.99.910 + current kernel is ok?
Comment 7 Felix Braun 2015-07-29 16:12:10 UTC
Sorry. I have to correct: video works nicely with totem both with 2.99.910 and 2.99.917.git The described behaviour only occurs with vlc both with 2.99.910 and 2.99.917 git. So I don't know whether vlc worked with any driver version.

Hrm. Still, there is something wonky going on. Some jpg files also display completely black with eye of gnome (eog). While they load normally in firefox or other image viewers (mirage).
Comment 8 Chris Wilson 2015-07-29 16:16:03 UTC
Can you try running xtrace (http://xtrace.alioth.debian.org/ maybe packaged as x11trace) on vlc and eog so that I can see what method they are trying to use to display?

Hmm, eog looks like it should be ok. I'll track down a 855gm and see if I can get set up. Can you point me at a failing image?
