Created attachment 139407 [details] example file ready to use SUMMARY The "Infinite 'update' loop with transform mask" (https://bugs.kde.org/show_bug.cgi?id=436642) has been fixed. But as I didn't answer about what to do (reopen bug or create a new one) and before I forgot this problem, I create a new one as the bug currently occurs only when transform masks are animated (so maybe related to animation, or not) STEPS TO REPRODUCE 1. Create a new document with following layers (or download attached file) [root] +-- Clone layer (of "GroupAnim") | +-- Transform Mask (animated) | +-- Group layer "GroupAnim" +-- Paint layer | +-- Transform Mask (animated) +-- Paint layer +-- Transform Mask (animated) 2. Hide group layer "GroupAnim" (optional) 3. Do nothing, just wait OBSERVED RESULT We can see activity every ~4s: - On all transform mask, even hidden transform masks - In status bar ("updating" progress bar) - Doing a 'top' in a terminal, many krita processes are created and raise to 100% EXPECTED RESULT Once transform mask is applied and projection rendered, no more activity is expected is nothing is modified on document SOFTWARE/OS VERSIONS Linux krita-5.0.0-prealpha-949e869-x86_64.appimage Grum999
Yeah, I can confirm this one with your test file. I had a hard time reproducing this on my own file, interestingly enough. At any rate, I'm labeling this one as a major/release blocking bug.
I think this one has been fixed by another commit and I can no longer reproduce it with the test file, so I'm closing this. If this specific problem persists, then please reopen with an update. Thanks again. Emmet
Hi I can confirm on last tested appimage (krita-5.0.0-prealpha-627782b-x86_64.appimage) that something has been fixed. It's not 100% fixed, but I think we can consider that problem is not noticeable anymore and bug can stay in "FIXED" status To be more precise: - Hide group layer "GroupAnim" -> We can see activity on hidden transform mask layers - Wait 4s -> We can see activity on hidden transform mask layers And then, no unexpected activity occurs anymore on hidden transform layers.
