Apart from this line:)

will not work!

It's actually working as expected - I just fixed the crash when OpenGL
initialisation failed so it falls back to the Qt painter.

Based on a comment from someone else yesterday, I now have a suspicion
that the root cause of your problem is the same as:

https://code.mythtv.org/trac/ticket/13538

While I've recreated the crash in that ticket, others have reported
that it manifests as falling back to OpenGL software renderer - ie.
llvm pipe, as in all of your logs. Fingers crossed!

Thanks
