Symptoms

I'm sorry in advance for a lackluster report but I'll do my best.
After loading in to the HUB (or being in any mission) the following issues occur while the game is running:

  • Screenshots become impossible. Programs like spectacle and ksnip immediately crash when the screenshot shortcut is pressed.
  • Steam ignores clicks. The bar at the top interacts to being hovered over but clicking does nothing. Clicking a few times causes a crash and after a restart it works normally.
  • The grid on this site becomes invisible on both chrome and firefox.
  • The kde's system settings refuse to open.

All of these issues resolve themselves shortly after the game has been turned off and I have been unable to reproduce the issues with any other game. There are also other issues like discord restarting itself but as that's not as reproducible I'm not as confident that that's the games fault.

Reproduction

Start the game, load in to the hub or any mission, attempt any of the things described in the Symptoms list. EX: Attempt to take a screenshot with spectacle or ksnip.

Again, sorry for not being more precise but I genuinely have no clue what's happening and wish you the best luck trying to find out.
Best regards -TwistedBOLT

It looks like this could be a KDE issue. System journal logs for an affected period would help to identify where/what the problem is — the Nvidia driver in particular is quite noisy in journal when something goes wrong.

If there's any kind of additional logging I could fetch or tests I could run I'm completely down to help, just tell me what to do.

I've ran the command "journalctl -f", reproduced the screenshot crash and then copied the log here:

Hope I did everything correctly.

eglMakeCurrent() in Spectacle fails with EGL_BAD_ALLOC, i.e. that auxiliary buffers cannot be allocated. I wonder whether the system runs out of VRAM or something.

I wonder whether the system runs out of VRAM or something.

Good catch! I just checked the Vram usage and it was fluctuating between 7.9 and 8Gb (Out of an available 8Gb) which is odd as when I ran windows on the same machine on the same settings it was significantly lower. Lowering the settings to medium does result in the Vram usage dropping to a comfortable 6Gb and none of the issues I had outside of the game occur. As it's stable at 5.8-6Gb it doesn't seem like the issue is a memory leak.

I'm not sure if I should close the thread or if the unusually high Vram usage is something worth looking in to. The game's requirements page does suggest 8Gb should be enough to run it at max settings.

Either way, thanks a bunch!
