Chromium hangs: GPU process hung

[Richard Eames]

Starting with a recent update to either my graphics card, or to chromium, it (chromium) will seem to hang after resuming from a lock screen. By hang, I mean it seems to refuse to redraw since it still responds to mouse clicks on the close button. Here's the stderr output on console:

ATTENTION: default value of option force_s3tc_enable overridden by environment.

This is one of the most irritating bugs I've come across. At the moment it's happening nearly every day on both my work and my home computers.
I just added additional information from my work computer in case it's useful.

The apport window that pops up after crashes lists this bug as a duplicate of https://bugs.launchpad.net/bugs/1402523 which does not exist.

One thing I do notice that crashes it: if I hover over the tab name, the tooltip will sometimes stay and become a white rectangle, if I then try to show another tooltip on the tab name, the browser locks up.

[Olivier Tilloy (osomon)]

@Richard: is that bug still affecting you with recent releases of chromium?

[Richard Eames (naddiseo)]

@Olivier: No, I haven't seen this bug in a while since I changed my video cards. (I do still see the tooltip graphical artefacts when hovering over the tabs, but it doesn't lock my browser.)

[Chris Carlin (crcarlin)]

@Richard: what graphics card showed the error and what did not? Did you ever notice hard drive thrashing while the window was refusing to redraw?

I MIGHT still be seeing this bug, but I'm not positive it's the one I've been seeing.

[Olivier Tilloy (osomon)]

@Chris: are you seeing the same errors in stderr as reported by Richard ("The GPU process hung" and "Lost UI shared context")?

[Richard Eames (naddiseo)]

@Chris: I'm not 100% sure, for my home machine it was either a Radeon HD 4850 or a Radeon R7 200 series.

I think this bug was "fixed" on both machines once I upgraded to Ubuntu 15.10. (Although on my work machine 15.10 caused a different system freeze bug starting with that release that didn't fix until I changed the graphics card again.)

[Olivier Tilloy (osomon)]

I’ll close this bug, please file a new one if you're affected by similar issues or if you're seeing crashes.
