Mangix, could you tell me what the size of the image is that you were working on? (in pixels)

[Mangix]

300 x 300

i cant reproduce it for some reason though

[Rick Brewster]

Very interesting ... I believe I've found the cause and have a fix for it.

Are you by any chance using a Tablet PC?

I recreated it. I just went back and forth real fast out of a 300x300 square. What do you think is happening, Rick?

P.S. - I am not using a tablet PC, just a normal desktop

Oh, it's a rounding error, basically.

For each brush stroke we figure out a rectangle that bounds it so that we can save a copy of the layer before we draw (for undo/redo). We do some adjustments to this rectangle to account for things like anti-aliasing and whatnot. Turns out that there isn't an extra clipping step in there at one point (i.e. chop off the parts of the 'save this area' rectangle that aren't within the bounds of the layer).

What's interesting is that this code has been largely unchanged for over a year and nobody else has reported a problem with it Good catch!

Thanks . I guess i love messing around with the program to find bugs.

Are you by any chance using a Tablet PC?

Im using an HP Pavillion so no.
