They happen whithout OpenGL activated , with OpenGL there is no display problem, but my computer is slower with OpenGL than without. Reproducible: Always 1131966 1 info 2011-06-16 17:59:26 +0000 I tryed to reproduce, but it's hard ... But opening this file http://david.revoy.free.fr/forums/krita/krita-bug-artefact_exemple.xcf with Krita does it everytime , I hope it will make easier the test for reproductibility of the bug. 1132690 2 sven.langkamp 2011-06-19 00:31:32 +0000 *** Bug 269456 has been marked as a duplicate of this bug. *** 1132865 3 sven.langkamp 2011-06-19 14:10:34 +0000 *** Bug 273844 has been marked as a duplicate of this bug. *** 1132867 4 sven.langkamp 2011-06-19 14:17:14 +0000 Git commit 7be561f4b4c5bd900133c0d82c2b8c6d51122cbf by Sven Langkamp.

I can't reproduce it now the way I did before, so it looks really fixed... And that's really help my actual project where I have large image to paint on. Cool ! 1137299 6 halla 2011-07-01 07:40:30 +0000 Well, seems that David has found some more presets that give issues, so reopening this bug since https://bugs.kde.org/show_bug.cgi?id=269456 is marked as a duplicate of this. 1139161 7 halla 2011-07-07 09:35:00 +0000 I've also seen artefacts from the brush outline myself. 1187500 8 dimula73 2011-11-20 15:37:14 +0000 I cannot reproduce these artifacts with the David's preset, could you check this now? 1224350 9 dimula73 2012-02-08 06:14:12 +0000 *** Bug 289174 has been marked as a duplicate of this bug. *** 1224352 10 dimula73 2012-02-08 06:15:42 +0000 When you paint with tablet and changes the pressure actively, the garbage still appears on the canvas.
