system freeze after full screen video viewing with Xorg on ultrawide monitor

[Krister Swenson]

1. open a video (either youtube or totem)
2. put it in full screen.
3. wait

Eventually (within minutes) the system will freeze in one of 2 ways.

1. There will be only blackness with no response (<ctr><alt><f3> even unresponsive).

2. There will be snow that shifts with keyboard and mouse interaction (see photo).

Thanks. That is a very helpful screenshot. It appears that only recently changed widgets/actors are rendered correctly. So this suggests a bug in mutter's buffer age logic, or the graphics driver.

Can you please:
  1. Run 'lspci -k' and attach the output.
  2. Run 'dmesg' (after the problem has occurred) and attach the output here.

Here's dmesg after a freeze of the system when watching a video with VLC. The strange snow did not show up this time:

I'm sorry for dumping the dmesg output into the thread. Here it is in a file. But it's from after reboot. Does this have the error messages in it from the previous session? Do I have to get a file from /var/log/ ?

[Krister Swenson (thekswenson)]

I tried using Unity instead of gnome-shell and am experiencing the same problem. Does this mean it's not a problem with mutter?
What is worse, is that this problems seems to crop up every day or so during work. In other words, everything will freeze except for the mouse even if I've never watched a video.

Could you please tell me details on how to get the best debug information for you?

[Timo Aaltonen (tjaalton)]

it's likely a kernel bug if the whole system freezes, so maybe try newer/older kernels:

http://kernel.ubuntu.com/~kernel-ppa/mainline/

[Krister Swenson (thekswenson)]

I'm able to interact with the system normally using the ctrl-alt-F3 terminal, although none of the methods listed in https://askubuntu.com/questions/455301/how-to-restart-gnome-shell-after-it-became-unresponsive-freeze/496999 properly restart gnome-shell. It seems to be related to graphics.

[Krister Swenson (thekswenson)]

More symptoms:

I can kill gnome-shell with "kill -KILL" from a ctrl-alt terminal.
The GDM screen then appears as usual. Logging in again, however, seems to hang on a blank purple screen.

The GDM screen appears normal but moving the mouse over the top-right corner to activate the menu results in EXTREME lag. The menu is usable but doesn't update for dozens of seconds after clicking on it.

Could this be a problem with XWayland?

[Krister Swenson (thekswenson)]

This bug is making it hard to work...
   I just had the system freeze up on me again after less than 5 minutes.
This time, when doing ctrl-alt-F3 I got the strange snow-like screen depicted in the attachement and none of the ctrl-alt terminals or GDM (at ctrl-alt-F1) showed anything but snow!

[Krister Swenson (thekswenson)]

Today the fuzzy screen depicted in the attachment appears spontaneously while using google maps. This time with a block around the pointer, that continued to move with the pointer.

[Krister Swenson (thekswenson)]

Gnome-shell will freeze at unexpected times when using the firefox browser. The symptoms are the same as when watching videos with totem. I've switched to chrome without having gnome-shell freeze on me.

Is there something particular about the way firefox 59 (Quantum) interacts with my graphics hardware?
