Created attachment 148300 [details] The file used in the recording. SUMMARY git f665ca6, but it has been happening for a while in nightly. I'm not sure since when. It happens with both canvas renderers : OpenGL, ANGLE. recording : https://imgur.com/fjkbabI STEPS TO REPRODUCE 1. Import an image. The file type(jpg, png, webp etc) doesn't seem relevant. 2. Transform it, confirm it by pressing enter or selecting other tools. 3. Undo&redo it repeatedly. OBSERVED RESULT Transparent Glitch appears. (If there's a background layer below, you'll be able to see it through in the glitched areas). EXPECTED RESULT There shouldn't be any glitches. SOFTWARE/OS VERSIONS Windows: Win10 macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Dmitry will look into this; it might have been solved by the fix for https://bugs.kde.org/show_bug.cgi?id=453243, but Dmitry is not sure.
It's not fixed yet. (tested in git f03ffc1)
Hi, acc4commissions! I'm not sure I fully understand what the "glitch" is, is this transparent rectangle appear only temporarily and heals itself or you need to do some specific action to make is disappear? I don't fully undersatnd from the video...
As far I remember it does not heal itself. I'm going to bed now but I'll later post more exact descriptions about how it heals.
If you do any action after, like changing zoom levels or touching the docker, the glitch heals itself. And after going through it one time, the glitch doesn't seem to happen again until restarting krita. (tested on git 716923c) Canvas Graphics Acceleration : on Renderer : OpenGL Using texture buffer
Hi, acc4commissions! Could you please check if the bug is still present in master? I have fixed a somewhat related bug 461109. Strictly speaking, it should be different from yours, but perhaps they had a commit cause...
Here is the link to the nightly package: https://binary-factory.kde.org/job/Krita_Nightly_Windows_Build/
Thanks for checking in, but nope. It still happens in the latest nightly. Not changes to the symptoms either.
Change back to ASSIGNED
Just adding as an info that this doesn't happen if the Canvas Graphic Acceleration is disabled. (Tested with the latest nightly git d9959df)
