           Product: krita
           Version: nightly build (please specify the git hash!)
          Platform: Other
                OS: Linux
            Status: REPORTED

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
