ADDITIONAL INFORMATION

Comment 1 Dmitry Kazakov 2023-10-02 07:25:44 UTC

Hi, Vyacheslav!

Could you check two things?

1) What happens if you save the image (into a backup location!) and open it again? Do the artifacts persist?
2) Could you also check if you have Canvas Graphics Acceleration enabled in Krita settings or not?

I have a feeling like this bug might be related to bug 452854...

Comment 2 Dmitry Kazakov 2023-10-02 07:26:15 UTC

Mark as waiting for info

Comment 3 Dmitry Kazakov 2023-10-02 07:32:16 UTC

The bug might also be related to bug 398689

1) When i save image and open it again, all ok (is no artifacts). BTW to remove artefacts need just make layer hide and visible again.
2) Canvas Graphics Acceleration - enabled

Comment 5 Dmitry Kazakov 2023-10-02 08:16:33 UTC

Hi, Vyacheslav!

If you disable Canvas Graphics Acceleration, do you still have the bug?

Could you please also attach the info from Help->System Information?

If Canvas Graphics Acceleration disabled looks like all ok.

Comment 7 Dmitry Kazakov 2023-10-02 08:51:43 UTC

Hi, Vyacheslav!

Could you please check one more thing for me? What happens if you do the following:

1) Enable Canvas Graphics Acceleration
2) Disable "Use texture buffers" option
3) Restart Krita

Does it "fix" the bug?
