Thanks for the details bugreport, i'll have to undust the amdgpu laptop to test, but some observations/questions first: - does the same problem also affect firefox 100 ? - i cant find a dev/dri call in the codepaths we use in firefox, there's one in linux sandboxing but we dont use it (cf https://searchfox.org/mozilla-central/source/security/sandbox/linux/broker/SandboxBrokerPolicyFactory.cpp#69) - from my understanding of the trace, iff you unveil /dev/dri then radeonsi_dri.so is used and the crashing codepath in swrast_dri.so isnt used ? or in both cases swrast_dri is used, and we should rather figure out why radeonsi_dri isnt found/used ? - of course i have zero objections unveiling dev/dri instead of dev/dri/card0 if it helps webgl on amdgpu, just wondering if it should be done only for the content process or also for the gpu process.
