Put it at NEW since there's a bt.
Markus/Zolnai: looking at git history searching from OGL, I thought you might be interested in this one.
It is fixed already in my OSX branch. I might need to backport some of these fixes to master to prevent some problems.
We are using the OpenGL canvas because the ones in the list before it are not implemented on OSX.
This only affects OSX. On Linux we use the cairo backend and on Windows the DX9 backend.
Markus Mohrhard committed a patch related to this issue.
It has been pushed to "master":
avoid picking the incomplete OGL canvas, fdo#83084
The patch should be included in the daily builds available at
http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More

Affected users are encouraged to test the fix and report feedback.
Just picked the commit from my feature/mac-opengl-fixes branch. That should fix your issue.
Thanks for the help. That did indeed do the trick, and allowed me to get on with reproducing the bug I was actually trying to reach :)
