Description Quiralta 2016-04-15 17:20:43 UTC

While using shift-leftbutton (stroke with a pen) to resize, the outline of the brush doesn't refresh, it gets "stuck" until I stop the stroke, then it "jumps" the final size, it looks like it flickers, some brushes like the "ink_brush_25" would work only if the stroke is very slow with some slight flickering, I found that the "Bristles_hairy" resizing works normal, no lag/flickering.

I am using Nvidia proprietary drivers on a Archlinux box, Krita build from source.

Reproducible: Always

Steps to Reproduce:
1.Open Document
2.Select a brush (Airbrushes are good example)
3.Resize by Shift+leftbutton (pen stroking)

Actual Results:  
Outline of the brush would not refresh, lag and flicker.

Expected Results:  
Smoothly increase decrease the size of the brush outline.

Hm... Here on my opensuse box, with Nvidia proprietary drivers, I cannot reproduce the issue. Something must be blocking the updates on your system, but it's really hard to guess what it is.

Boud, I'm afraid is not the same as 354718 which I saw a while ago, I am on a "clean" build with no customized presets and all except for one of the presets lags. Krita 2.9 (which I have also installed along side the alpha) behaves normal. Not a big issue though, as you say maybe is my system. Will wait for a beta state, may be things get better there : )
