Follow-up Comment #3, bug #18823 (project mypaint):
A little bit of background info: MyPaint will do the zoom-out fully in
software (via software mipmap code) if the zoom level is a multiple of 2
(every 2nd zoom step).
For the zoom-levels in-between (and also for rotation) it will ask the Cairo
library to render the transformed bitmap, which has the ability to use
hardware acceleration (via X11 backend at least).
We can control the hardware flags (to some extent) for testing. Maybe you can
find something out by enabling the commented-out code that sets interpolation
flags, in gui/tileddrawwidget.py line 540? Maybe the problem happens only when
translated by half a pixel, or something similar?
