Created attachment 137489 [details] kra file with animated paint and transform layer I used SUMMARY 5.0.0-prealpha-1222798f0a In several versions of Krita 5 prealpha, when I have tried to merge a layer with a transform mask I get back a blank layer. If it is an animated layer I get back frames in the same place but nothing in each frame. This happens for 'Flatten Layer', 'Flatten Image' and 'Merge with Layer Below' involving an active transformation mask. Merging works as expected if the transformation mask is not visible or hasn't been moved to make a transformation during the merge. STEPS TO REPRODUCE 1. Draw on a layer 2. Add a transform mask to the layer 3. Transform the layer using the transform mask (toggle on and off the layer to show the drawing again due to Bug 435296) 4. Merge the layer and transform mask together OBSERVED RESULT Layer becomes blank without any drawings from before the merge EXPECTED RESULT Layer and transform mask should merge together, drawings should be where they were transformed to with the transform mask before the merge. SOFTWARE/OS VERSIONS Windows: Windows 10 ADDITIONAL INFORMATION Worked in 4.4.3, see this comment for another explanation: https://www.reddit.com/r/krita/comments/g3ri8b/animation_moving_multiple_frames_of_a_layer/fnu7hhn/
I can confirm this, as described, for the Apr 11 5.0.0-prealpha (git 1222798) appimage. It does not happen with the 4.4.3 appimage or the Apr 11 4.4.4-alpha(git 9180bae). For the 5.0.0-prealpha, when the inage is opened thre transformed frame content displays correctly but disappears after a few seconds. it can be restored by clicking on any frame in the Timeline or by toggling the visibility of the transform mask. It then disappears again after a few seconds.
Git commit 2edd4823e656cc0c4d3177aaeb8000165d1e1606 by Eoin O'Neill. Committed on 12/04/2021 at 20:14. Pushed by eoinoneill into branch 'master'. Fixed two bugs regarding animated content and transforms. 1) Flattening a layer w/ transform content will now properly render out all keyframes with proper transform (no more blanks). 2) Transform masks will always render properly on animated layers when there are no keyframes on the transform mask, but there is content on the transformed layer. There were certain circumstances where no projection update was applied at all, which was not intended.

Git commit 348d57b23bffaca39c51e0b558460158c5e745c1 by Dmitry Kazakov. Committed on 20/05/2021 at 11:00. Pushed by dkazakov into branch 'master'. Fix rendering of the final projection if the transform mask There was a misprint in KisTransformMaskAdapter::transformDevice(), which called a wrong function override.
