            Bug ID: 483317
           Summary: Disabling multiple layers at once is displayed
                    incrementally
    Classification: Applications
           Product: krita
           Version: 5.2.2
          Platform: macOS (DMG)
                OS: macOS
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: Layer Stack

  Target Milestone: ---

I'm used to toggle layer visibility to see the difference between what I add
and the underlying image.
~Some...~ most of the time "what I add" is on several layers. So I disable them
all at once with a keyboard shortcut `toggle layer visibility`
Since a while now (maybe since it got taken into account in undo history) when
disabling several layers, I see them being turn off one by one.
This really defeats the toggling effect to see the before/after difference.
Enough for me to go and group everything I want to toggle at once (in a group
layer).
So then I need to paint in a layer, select the group, toggle, go back to the
layer to paint. Even doing so with keyboard shortcuts, this slows down the
work, adds mental overhead and "boilerplate" manipulations...



STEPS TO REPRODUCE
1. Create a big canvas like 10k*10k
2. Add something like 5 totally distinguishable layers so you can see the
difference while toggeling
3. Select all layers and toggle their visibility at once (I do it with a
keyboard shortcut)

OBSERVED RESULT
Layers disappear one by one.

EXPECTED RESULT
Layers disappear all at once.
Yet, hot (instant) coffee appears on ~my~ the table.
