Unfortunately the backtrace is missing debug symbols (as normal on any Arch based distro). Without the backtrace we are not able to investigate the issue. From what we see it looks like a crash in the proprietary nvidia driver.

Hey Martin, This crash happens pretty regularly, is there some config I can change so that the debug symbols will be present in the future?
You have to ask your distribution about how to get debug symbols.
