Created attachment 124591 [details] Example file 32-Bad.kra SUMMARY This has been observed before in the forum posts (one a long time ago and one recently https://forum.kde.org/viewtopic.php?f=139&t=163737 ) and for me it only happens with the Linux appimage for all versions that I tested from 4.2.6 to the Dec 17 4.3.0 prealpha (git 08e7240). It does not happen with the corresponding Windows portable zip builds running on Windows 10 but it does happen if I run those portable zip builds under WINE on Linux. STEPS TO REPRODUCE 1. Start krita and make sure graphics acceleration is turned on. 2. Make a 32 x 32 animated image like 32-Bad.kra as attached 3. Note that this does not play well at all. 4. Turn off graphics acceleration (and restart krita) 5. Note that 32-Bad.kra now plays well. 6. Repeat the above with an additional large 'blob' of paint in a blank area that changes from frame to frame, like 32-Variable-Blob-Good.kra as atached. 7. Note that this plays well with graphics acceleration turned on. 8. Repeat the above with a large 'blob' added that does not change from frame to frame, like in 32-Fixed-Blob-Bad.kra as attached 9. Note that this does not play well with graphics acceleration turned on. 10. Turn off graphics acceleration (and restart) then note that 32-Fixed-Blob-Bad.kra plays well. OBSERVED RESULT See Steps To Reproduce. EXPECTED RESULT They should play as painted regardless of the graphics acceleration setting.

The problem happens only when "On-disk Animation Cache" function is used. As a temporary workaround, try to switch to "In-memory Animation Cache" in Settings->Performance->Animation Cache.

Fix animation rendering problem on small images (< 100px in size) We should not shortcut to full-frame-copy based on approximation, it may hide some pixel-perfect changes, which are important for the user.
