--- Comment #1 from Boudewijn Rempt <b...@valdyas.org> ---
Hi,

Yes, this is known. We warn about this every time we announce OSX packages:
because Apple has decided not to support the compatibility profile of OpenGL
3.x, Qt's OpenGL integration doesn't work properly on OSX. It needs access to
the functions Apple doesn't expose when asking for OpenGL 3. On the other hand,
without access to OpenGL 3, the new Instant Preview feature and the
high-quality canvas zooming isn't possible. 

Since we cannot magically improve Apple's broken OpenGL support, we need to
rewrite Qt's opengl integration, and that's what is going to happen between now
and Krita 3.1.  

For 3.0 final, we'll likely return to using just OpenGL 2.1, which means tool
outlines but no instant preview/high quality zooming on OSX.
