[krita] [Bug 386927] Brush first draws a straight line
https://bugs.kde.org/show_bug.cgi?id=386927 Azher Krimson <krimsan...@gmail.com> changed: What|Removed |Added Resolution|--- |FIXED Status|UNCONFIRMED |RESOLVED --- Comment #14 from Azher Krimson <krimsan...@gmail.com> --- Bug was probably due to an improper driver upgrade, thank you for your help. As obvious as it may sound I had not tried uninstalling and reinstalling the driver, because I thought the fault couldn't possibly come from it as every other program (including FireAlpaca, Photoshop, Paint and Sketchpad) were working perfectly fine. Thank you for your time !

https://bugs.kde.org/show_bug.cgi?id=386927 --- Comment #12 from Azher Krimson <krimsan...@gmail.com> --- Driver is updated to version 6.3.25-5 which should be the latest The problem happens whatever Krita's pointer API is set to and whether or not windows ink is on. Despite the log showing the driver malfunctioning, I must mention that photoshop on the exact same machine does not experience this issue at all and draws smooth lines from the get go.

I have an Intuos Pen and Touch small ( CTH-480 ) I have added system information to a separate comment. I know it doesn't change that much but it has fixed some lag issues for me in the past so that was one of the first fixes that came to mind. But thanks for the tip ! -- You are receiving this mail because: You are watching all bug changes.

[krita] [Bug 386927] New: Brush first draws a straight line
https://bugs.kde.org/show_bug.cgi?id=386927 Bug ID: 386927 Summary: Brush first draws a straight line Product: krita Version: unspecified Platform: Other OS: MS Windows Status: UNCONFIRMED Severity: major Priority: NOR Component: usability Assignee: krita-bugs-n...@kde.org Reporter: krimsan...@gmail.com Target Milestone: --- Created attachment 108871 --> https://bugs.kde.org/attachment.cgi?id=108871=edit Strokes showing the bug's effect. Brush is registered as a straight line for approx. 300ms from the start of the stroke. This is true of both mouse and stylus, and of every single stroke. I have flagged this as a major bug since this renders me effectively completely unable to draw anything. The only way to fix it seems to be to wait out the lag period, then trace. I should mention this doesn't happen in Photoshop CS6 on the same machine, and that I have allocated 100% RAM to Krita and set it to run realtime. These are the only settings I have modified from the defaults. Krita is also running from an SSD with a comfortable 32G of empty memory. -- You are receiving this mail because: You are watching all bug changes.
