I can confirm this on 4.3.0-prealpha (git 02bdc53) Git commit a8716a2573d098e0103305e4bfaf0824647844a5 by Wolthera van Hövell tot Westerflier. Committed on 14/08/2020 at 12:59. Pushed by woltherav into branch 'master'. Align quickbrush dabs to outline. For some reason, the quickbrush dabs tend .5 towards the lower right, so we subtract that from the brush position to align them to the cursor. This also increase the cursor size, as it was not including the extra pixel for antialiasing.

Created attachment 122855 [details] Screenshots showing the issue SUMMARY The actual area that the Quick Brush Engine (using "b)_Basic-1" brush Preset) doesn't match the cursor outline. It seems the size is one pixel larger then it should be, going out of the previewed outline on the right and bottom. This makes it harder to draw and especially erase precisely with this brush because the center of brush and outline don't match. STEPS TO REPRODUCE 1. Choose "b)_Basic-1" brush preset at some smaller size (like between 5-10px) 2. Zoom into the canvas a bit (200-400%) to better see the issue 3. Make sure your mouse doesn't move and click somewhere on the canvase OBSERVED RESULT When you compare the cursor outline with painted dot, they don't match properly, the dot seems to go 1 pixel outside to the left and bottom. It becomes more apparent when painting over with a different round brush like Basic-2_Opacity (see attachment) EXPECTED RESULT Painted area should touch the cursor outline equally on all sides.
