Game freezes at the end of E1M6

[xyz32]

The game freezes at the end of E1M6 (entering the last portal)

The game shows the level completions status screen and freezes before loading the next map. Map E1M7 works in a multiplier match.

I used the latest git code and the latest vulkan sdk 1.0.21.1 OS: Fedora 24 CPU: AMD 8 cores GPU: NVIDIA (latest proprietary drivers) RAM: 16G

There is no console output during the crash. This is the console output after the game starts:

Does this happen if the map is loaded with map E1M6 as well or only if you play the game from the beginning?

[xyz32]

Yes, it only happens when played from the beginning. Using map E1M6 works.

Sorry for the late response

Got some more info. The freeze only happens if at the end of the level when the status screen appears, you start pressing the fire button to jump to the next level. If you let the status screen to stay on for ~10 seconds and then press the fire button everything is good. On the other head if you wait for a long time 40-60 seconds and then press the fire button the game will also freeze.

Actually, I had the freeze once, and each other 2 times I loaded at the spot before I entered the portal in the floor, I mashed fire right away. Hard to pin down for sure. I must have loaded it 10 times. I am keeping the save before I enter the portal in case any more testing is needed. I am using a build from 1 day ago. I can nab the commit if need be from my Debian package.

Update: I captured what was going on by tailing /tmp/dumps/steam_stdout.txt on SteamOS. I probably had to do this about 15 times to get it. Don't pay too* much attention to Segmentation fault /usr/games/vkquake -basedir "${BASE_DIR}"`, as that happens each time I exit the game, without damange to saves et. At some point that should be looked at.

I believe there is a bug with SDL / how Vulkan handles it? When the crash happens, sound glitches, the loading bar also gets stuck. The sound then stutters, and the game crashes.

I believe it's an issue with submitting a command buffer referencing already freed resources. Getting validation layer reports as well and sometimes crashes. Will be fixed at some point, just needs some debugging.

[Novum]

This should be fixed with 30db23efe70d6df53969b393aaf0d9fd51f6f2c8

Confirmed, thank you.
