--- Comment #5 from Alvin Wong <al...@alvinhc.com> ---
(I thought it might've been related to coordinates handling with the pixel
iterators used in wraparound mode, perhaps with all the division and
rounding... but I can't confirm anything.)
I just tried this again with a new build using a new file at 1600x1200px and
while the performance is indeed way better, the updating of the brush stroke
gets all blocky when drawing outside the main canvas. And the weird thing is
that after having drawn outside the main canvas, the blocky update remains even
when drawing on the main canvas area (which hadn't appeared before drawing
outside the main canvas).
I don't feel that it's an issue with OpenGL performance, but I'll need to
experiment a bit more. Reopening for now...
