The crash is still happening with master 043d14db30. Backtrace is similar but slightly different, I've updated the attachment in <a href="show_bug.cgi?id=103915#c3">comment 3</a>. > 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?
