SUMMARY Random noise filter not being applied or updated correctly. STEPS TO REPRODUCE 1. Draw on a raster layer 2. Add Filter - Random Noise to the layer, either destructively or as filter mask 3. If added destructively directly to the layer the issue is visible immediately, if added as filter mask change parent layer Opacity or Blending mode to see the issue 4. Additionally if added as filter mask, draw new pixels after step 3 OBSERVED RESULT When applying Random noise filter directly to the layer it only applies it in a box shape around the pixels on the layer, not the entire layer. And when applying it as filter mask it affects the entire layer but does not update correctly when changing parent layer opacity, blending mode or when drawing new pixels to the layer, leaving artifacts around new pixels or updating only box shape area around current pixels when changing blending mode/opacity. Turning filter mask visibility off then back on will update the filter correctly. EXPECTED RESULT Applying the filter to the entire layer and automatic updating in case of filter mask.

I can only reproduce the 'destructive' version, but not the filter mask version, but reproduce I can.
(In reply to wolthera from comment #1) > I can only reproduce the 'destructive' version, but not the filter mask > version, but reproduce I can. Hmm, weird... I can reproduce it every time both ways. But when applied as mask only when I add extra pixels or change layer opacity/blending mode. Also found out if I turn off the parent layer, the noise from the random noise mask stays active everywhere except for the box shape around where parent layer pixels were.
Been fiddling around with filters in general and I found out more bugs that are probably closely tied to this report. Unsure if I should fill a new report or add more info here but for now I'll just add here some of the issues I found out. Generally adding filters through Krita > Filter menu (or their corresponding shortcuts) will have a weird behavior. Some filters don't show updated preview on canvas or when applied destructively (OK button in the called menu) will not apply at all (as if no change was made to curves and such). While when applying same filter as mask (Create Filter Mask button in the same menu) will show changes on the canvas but only after creating the mask, not in preview, and later further adjusting (F3 on added filter) will work as it should showing correct preview and everything. Some filters have issues only when applied to certain layer type, such as filtering a Filter Layer or Fill Layer while they work correctly on Paint Layer (ex. Color Adjustment will work on Paint Layer correctly but not on Filter or Fill Layer while Random Noise seems to be incorrect on most layer types). Many, if not all, filters have similar issues when added this way but when added through Layers widget (+ sign on the bottom or settings drop down then add > filter mask or their corresponding shortcuts) will work correctly. Random noise still seems to have an issue if changing parent layer opacity no matter which way the filter is added.
