When painting in the main canvas, the WA mode copies on the same row updates in real time, but not those on the other rows -- they are delayed and only updated in intervals, sometimes becoming outdated until the next mouse move. Probably a regression from https://invent.kde.org/graphics/krita/-/commit/6a5e83d1f4985998b33a059245dcafe5d5b98160 Tested with commit 5f8eb59328
Git commit f5255d4e73d0a92e5e48f823a89e17436d286394 by Dmitry Kazakov. Committed on 22/09/2021 at 12:32. Pushed by dkazakov into branch 'master'. Fix artifacts on the canvas when the display scaling is set to 110% The problem is that we do "cropping" of the painted area twice during one frame. Firstly, we enable stencil test to avoid too much pixels to be rendered. And secondly, we limit the number of tiles that are rendered on screen. And these two limit must agree in how they do rounding.
