I am experiencing quite random crashes when I'm streaming either video or audio files through the browser. It isn't the whole system that crashes, it's actually only the display that stops. The audio generally keeps playing and even the mouse is still responsive. If I restart lightdm, everything works okay, but it's obviously pretty annoying.
The issue occurs in both firefox and chrome.
I can't seem to figure out what's wrong. Dmesg and also syslog don't really show any visible issues.
Is there something that I could do?
