below is the IRC paste from the discussion about this issue with animtim.

Basicly when making stroks with grid brush on a non-blank layer, when you make a few strokes and then undo,this does not update on the canvas.

When you save and re-open however the strokes are indeed gone. So it is a canvas refresh issue.



23:00:07 - Bollebib1: can some one confirm (possible will have to repeat this tomorow when there's more people..)
23:00:07 - Bollebib1: choose a grid brush
23:00:07 - Bollebib1: make a few strokes
23:00:07 - Bollebib1: try to undo
23:00:07 - Bollebib1: ->my result is that some strokes of the grid brush doesn't get undone
23:03:17 - Animtim: Bollebib1: here it works fine, all grid-brush strokes are undone properly
23:03:28 - Bollebib1: strange
23:03:43 - Bollebib1: maybe there is an update to do still..
23:04:23 - Bollebib1: I only need to make 3 consecutive strokes to get the issue
23:05:27 - Bollebib1: but it's only the canvas
23:05:27 - Bollebib1: ,when I save, and re-open the strokes are not there..

23:07:44 - Animtim: Bollebib1: hum, I can actually reproduce but only if painting on the white background layer (I first tried on new layer, as it's a habit I always do..)
23:08:28 - Bollebib1: I get it on a transparent layer as well,but I already painted on it next to it so maybe that's a factor
23:09:10 - Bollebib1: i'll talk to boud about it tomorow,and then make a report
23:09:45 - Animtim: yep it is indeed: on pure blank layer it doesn't seem to happen, but with a few strokes from another brush engine before, it then happens.
