No response

Expected Behavior

For OBS to use the integrated GPU as default

Current Behavior

Window pops up then disappears (core dump)

Steps to Reproduce

  1. Boot system with initial GPU device as the dedicated card
  2. run DRI_PRIME=1 com.obsproject.Studio (set DRI_PRIME to non-default iGPU)
  3. A window should pop up then close immediately after

Anything else we should know?

For using gdb in the Flatpak (src):

$ flatpak install org.freedesktop.Sdk.Debug com.obsproject.Studio.Debug # Optional: Install OBS Studio debug symbols
$ flatpak run --command=sh --devel com.obsproject.Studio
$ gdb /app/bin/obs

Once gdb ready, run by entering the command r and reproduce the crash. Once done, you should be able to enter the command bt. Message the output of this command. You can quit by entering the command q.

This looks like a bug in mesa to me.
