Subject: [PATCH 16/20] UI: Don't create obs_display when QTToGSWindow fails
|
|
|
|
Right after showing the OBSQTDisplay widget, it may happen that a
|
|
wl_surface is not yet created and attached to the window. When this
|
|
happens, creating the OBS display results in a crash.
|
|
|
|
Make QTToGSWindow return a boolean, indicating success or failure, and
|
|
don't create the OBS display on failure.
