Stall followed by crash in Alpha Labs 4

[dominalien]

I'm playing the game and have a 100% repeatable (on my system...) stall. The game just freezes, sound continues playing. Now, if I switch to another workspace and back it starts running again, but then shortly afterwards stalls again and usually crashes. Up until now the game was 100% solid.

The area is called EFR Junction 6 and it's a place with corridors with no floor and floating platforms. I can provide a save just before the area, the stall happens within 5 seconds to a couple of minutes, I haven't been able to get through the area yet.

The system is Ubuntu 20.04 (upgraded yesterday, it was happening also before on 19.10), hardware is Nvidia 330M, driver is 340.108. I verified the checksums of the pak files I have and they all check out.

Here's the output from the terminal after a stall, another stall and crash. I took two screenshots in the mean time, one of them when the game was stalled, so this at least works. There are a couple of warnings, I don't know if they have anything to do with the problem.

Just wanted to add that I managed to get through the area just now, saving every 5 seconds and hoping it doesn't crash and right after I get out of the place and get to the corridor where there's the big window to the area where the spider woman comes out the game seems to not crash any more. I was able to kill the boss and exit the level no problem.

[DanielGibson]

Could you provide the savegame right before the affected area (and maybe a screenshot of the affected area so I run in the right direction)? The savegames should be in /home/domin/.local/share/dhewm3/base/savegames/ and if you put the relevant files in a .zip or .tar.gz archive you should be able to attach them to a comment here in the github issue.

Thanks in advance!

Here you go. Just go through the door and onto the floating platform towards here: shot00003.zip

I couldn't really reproduce this, neither on XUbuntu 18.04 with Geforce 970 and drivers 440.64, nor with XUbuntu 20.04 with a Radeon RX580 and the open source drivers.

Your terminal output also looks normal (mine looks very similar), so I have no idea what causes your issues :-/ I don't currently have time to set up a "normal" Ubuntu (instead of XUbuntu), maybe that's the difference between our systems that causes the problems..

Can you try building dhewm3 yourself from source, with the latest source from git? It's done like this:

1. sudo apt install build-essentials git cmake libsdl2-dev libopenal-dev libjpeg8-dev libvorbis-dev
2. git clone https://github.com/dhewm/dhewm3.git
3. cd dhewm3 && mkdir build && cd build
4. cmake ../neo/
5. make -j4

Then the dhewm3 executable is in dhewm3/build/ and you can start it with ./dhewm3 in the terminal.
If it can't find the game data, you can tell it where to find it with:
./dhewm3 +set fs_basepath /path/to/doom3data/
(of course you need to change /path/to/doom3data/ accordingly)

[dominalien]

I compiled the git version, it does the same thing. I also tried on another, even older laptop with Nvidia 8600M, driver 340.107 and Ubuntu 19.10 and it behaves the same. I'll test some more on different hardware.

[DanielGibson]

Thanks for checking that out!

If it's not too much work, can you test this with different desktop environments (esp. XFCE)?

[HarrievG]

The only thing I can do here, is try to reproduce on win10 with geforce2080ti.. When i have tried a repro ill report back here.

[DanielGibson]

@dominalien: does this still happen with current master code (and possibly updates installed on your system)?
