Hi, Thierry! Could you check is disabling openGL optimization makes lines better? You need to go to Preferences->Display->Canvas Graphics Acceleration, uncheck the checkbox and restart Krita.

That sort of line 'segmentation' can sometimes be seen with quickly drawn tightly curved lines and is often due to a low reporting rate from the drawing tablet. Since you have no problems with a different painting application, it's obviosuly not just the tablet hardware itself. You also seem to have limited pressure resolution judging by the step variations in line thickness (assuming you're using a brush preset where size varies with pressure). That may also be due to a slow effective input reporting rate and a quickly drawn line with rapid pressure variation. If you draw the line very slowly with slow variation of pressure, does that give you smoothly curved lines with smooth size variation? Which drawing tablet are you using? Have you tried installing the lastest tablet driver from the manufacturer? I don't know about Mac computers or MacOS so I don't know what options are available to try in the tablet settings. This problem is caused by our openGL implementation on ancient apple openGL API. e are currently sutdying options to fix this as we know how frustrating it is to get it to behave. There are work arounds as see on the bug im marking as duplicated of, but they have drawbacks. *** This bug has been marked as a duplicate of bug 414025 *** |
