--- Comment #8 from Dmitry Kazakov <dimul...@gmail.com> ---
Git commit 08fd3aa8e554557728f60f8571e51364070c09e8 by Dmitry Kazakov.
Committed on 25/03/2016 at 12:08.
Pushed by dkazakov into branch 'master'.
Fix "openGL lag at zoom 2000 + rotation"
The problem was not related to the openGL actualy. It was caused
by the implementation of QPainter::clipRegion() which generated
20k+ rectangles from a rotated rect when rotation angle was near to
a 0 or 90deg.
WARNING for the future:
Never use QPainter::clipRegion(). Use KisPaintingUtils::safeClipRegion()
instead. It workarounds the issue returning a bit bigger rect.
Fixes T1446
