(In reply to Nicolai Hähnle from comment #2) > Could you try if it also happens with Mesa master? The crash is still happening with master 043d14db30. Backtrace is similar but slightly different, I've updated the attachment in comment 3. > If yes, could you provide an apitrace? I didn't have any luck here. I built a 32-bit build of apitrace, then set the steam launch options to "/home/toojays/src/apitrace/build/apitrace trace %command%". This resulted in a trace file containing two bytes: "at". Likewise when I tried launching steam like: DEBUGGER="/home/toojays/src/apitrace/build/apitrace trace --verbose" steam steam://rungameid/391540 I also tried running Undertale directly like: LD_LIBRARY_PATH=/home/toojays/.local/share/Steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu:./lib ~/src/apitrace/build/apitrace trace ./runner Still no good. I can see from the core that apitrace had some data for us, but for some reason it couldn't get it out in time?
