Bug ID: 422804
Summary: Layer Mask visibility on/off has no effect in latest

Mask Problem .kra file for illustration
SUMMARY
This bug is not present in the 4.3.0 beta-2 appimage but is present in the
4.3.1 alpha (git 741ba2a) and the 5.0.0 prealpha (git ce3a1a3) appimages.
If a layer mask or masks are applied to a paint layer then they work but
turning them off/on has no effect.
I attach a .kra file for illustration and investigation.
STEPS TO REPRODUCE
1. Apply one or more layer masks to a paint layer. Use Transparency, Filter or
Transform Masks or any combination.
[Note that the masks have the expected effect.]
2. Turn off the visibility of any mask or masks.
[Note that this has no effect on the on-screen image.]
3. Turn off the visibility of the paint layer and turn off all masks then turn
on the visibility of the paint layer.
[Note that the mask visibility setting is now correctly shown]
4. Repeat step 3. and do some combination of on/off for different masks.
OBSERVED RESULT
The change in mask visibility is only shown after the paint layer has it's
visibility turned off then on.
For a transform mask, there is an artifact of the untransformed state that
persists for a few seconds before disappearing.
For a gaussian blur filter mask, there is an artifact that does not disappear
unless the gaussin filter mask is reapplied and the paint layer visibility is
turned off then on.
EXPECTED RESULT
Changing the visibility of the masks should give a rapid change in on-screen
appearance with no artifacts.
