(Video example)

(I'm on Ubuntu 14.04 LTS with Krita 3.1.0)

1) Switch to the "Shape_fill" brush.
2) Select "Tool Options (docker) > Stabilizer".
3) Paint a few strokes.
4) Press the key "E" to enter the brush eraser mode.
5) Try to erase the painted strokes.

Expected Results: erase the painted strokes.

Actual Results: brush doesn't erase, BUT, if you keep erasing without lifting the pen, after a few seconds it'll catch up.

---
Note 1: it seems that sometimes Stabilizer makes the Shape_fill" brush unresponsive also when straight painting (not only erasing).

Note 2: I've tried by disabling instant preview, but I'm getting the same result.

Also, the issue disappears when painting with rapid gestures (Stabilizer enabled).

Hi Mvowada,

I'm really sorry... But I cannot reproduce this one either, at least not on my plasma5/opensuse system. I copied the exact settings from your video but everything felt nice and snappy :-(. Would it be possible to add another window manager, something simple like fvwm2 to your system and test whether that makes a difference?

Oh, I think I get it now... But I don't think we can do anything about it: when the stabilizer is on, you always need to move outside the stabilizer area before a brush begins to paint. That might feel a bit weird when using a shape brush, but it's not unexpected.
