[0.16.15] Freeze in Linux, probably related to switching workspaces

[luc]

When switching workspaces (ctrl+alt+left/right/up/down arrow keys in many distributions), the game sometimes freezes. I'd guess around once every 20 times. I use it to switch between sets of applications, and Factorio has its own workspace since it's fullscreen.

When freezing, I can still go back to the game and see the screen. Music continues to play. I've tried looking at call stacks and stuff, but I'm not good enough with gdb to properly do this. I've managed to capture a core dump during one of those freezes so you can inspect its state (that's the purpose of core dumps right?), but it's 339MiB gzipped (2.1GiB uncompressed), just a tiiiny bit too large to post on the forum I can host it on my website and send you a PM with the link, if you'd like to take a look at it. I can't figure out what call it gets stuck on (mainly the multithreading is throwing me off), so I'd be curious if you can figure it out.

The log shows nothing out of the ordinary:

^C1325.234 Received SIGINT, shutting down
^C1326.478 Received second SIGINT, terminating immediately

As you can see, it detects the SIGINT but does not shut down properly. After a second Ctrl+C (SIGINT) it terminates. In this case I hit Ctrl+C twice immediately, but also if I wait multiple minutes after the first Ctrl+C, nothing happens. If I've been playing for longer, there are more log messages of course (such as autosaves), but never anything that seems related to the freeze.

This has not happened in previous versions, though of course it might have been introduced in 0.16.13 or whatever and I just hadn't noticed yet.

It seems to happen with any map, large or small (the one I loaded, game16.zip, was one with only a few seconds of playtime).

If I can provide anything else, let me know.

Edit: Just tried the PVP scenario, that looks like lots of fun! If only I had friends to play with Anyway, just happened there too, so that confirms it's not specific to loaded games but also to unsaved, generated games.

Edit 2: also happened in main menu just now.

Edit 3: it also happened without switching workspaces (or alt-tabbing or anything) now, so I have no identifiable cause anymore (so I removed it from the title, title used to be "Freeze when switching workspaces in Linux"). I can't seem to play anymore at all. I'll try to reboot and stuff, and post back later.

Edit 4: So after rebooting, I could play online for about 15 minutes (wanted to try the pvp with someone, but don't have much time) and that worked fine. Now I tried to switch workspaces a bunch of times, just to check whether rebooting resolved it completely, and the bug got triggered again. So it does seem to still occur, and it is almost certainly related to switching workspaces (even if not a direct cause). What's new is that it actually gives me an error:

Hope this helps! I also still have that core dump in case you're interested.

[Oxyd]

I've managed to capture a core dump during one of those freezes so you can inspect its state (that's the purpose of core dumps right?), but it's 339MiB gzipped (2.1GiB uncompressed), just a tiiiny bit too large to post on the forum I can host it on my website and send you a PM with the link, if you'd like to take a look at it. I can't figure out what call it gets stuck on (mainly the multithreading is throwing me off), so I'd be curious if you can figure it out.

Can you post the output of `thread apply all bt` on the core? And yes, if you could host the core somewhere, that'd be helpful.

I will PM you a link of the core dump

[luc]

I just made the mistake of hitting the printscreen button, which blurs focus for half a second. The game froze again

So I guess it's not workspace-switching or alt-tabbing, but just losing focus in general.

[Oxyd]

After a bit of searching, this looks to be a bug in Mesa. Can you test other OpenGL programs if they have the same issue? The bug report suggests that it should be fixed in the latest X.org packages – does updating fix it for you?

[luc]

Thanks for the follow-up! I still need this laptop to be 100% stable until next Thursday for a project, after that I was planning to upgrade to Debian Buster anyway (so from Debian's stable to testing branch), so I should get the latest version of everything again. I'll also have time to look into other OpenGL programs (right now I'm not sure which programs I could use to test). I'll report back next week

[ema]

I got the freezing on losing focus too (only when in fullscreen mode). This behavior appeared after I had updated my system but not factorio, so I guess this is more evidence for it being that mesa bug.

[luc]

I just upgraded to Debian Buster. The version of libgl1-mesa-glx is now 17.3.3-1 (upgraded from 13.0.6-1+b2).

In the comments of the bug you linked, it is mentioned that "Upgrading xserver-xorg-core to 2:1.19.1-1 or newer and restarting X should fix the problem." My xserver-xorg-core package is now at version 2:1.19.6-1 (was 2:1.19.2-1+deb9u2). They also mention that "Iconifying and un-iconifying glxgears four or five times is enough to get it to reliably hang." I assume that iconifying means minimizing or defocussing or something. Neither reproduces the issue for me (after upgrading, that is).

The issue in Factorio still persists, but it's wonky. Each time I start Factorio, there seems to be some chance that it will happen again. If it doesn't happen, I can alt-tab 10 times and it'll just run. When it does happen, a single alt-tab is enough to make it hang. I cannot reproduce this with glxgears (it never hangs, no matter how many times I start glxgears).
