There are two related commits here
3db436f : Prevent segfault when OpenGL is set on remote X11 session.
e9daa4e : Fix frontend failure when using QT painter with OpenGL video
Can you confirm for me:
You are not connecting remotely and trying playback (that is one thing
this tries to prevent)
What is the value of the environment variable DISPLAY before you run the
This is how DISPLAY is checked in this case:
DISPLAY not set should allow playing
DISPLAY=:x or DISPLAY=unix:x should allow playing
DISPLAY=hostname:x should prevent playing (this indicates remote login)
I think DISPLAY maybe used differently in OSX
I can bypass the checks in OSX if they are not working there.
Maybe you can check the scenarios for me on OSX using a version that
does not include either of the above 2 commits (e.g. fixes/0.28 or a
build before e9daa4e):
1. If you set ThemePainter to QT and Video display profile is set to
OpenGL, can you successfully play recordings and videos? With Linux you
cannot, the video is invisible, you just hear the audio and there are
thousands of error messages in the log.
2. If you set Themepainter to OpenGL can you open the frontend remotely
from another terminal using ssh and X11 forwarding? With Linux that
causes a segfault.
if case 2. if the frontend will not open successfully please check the
value of DISPLAY on local and remote sessions so that I can use
