Odd lines with Undo - 10.04

[cgirerd]

ver 10.04

I've noticed that when I'm in a camera view (elevation, overview, vector, etc) and I select "undo" for something, lines like a sort of angled grid start drawing over the top of the picture as Chief thinks about the undo. Finally the undo happens, and I refresh the screen and the lines go away, but I never noticed that until ver 10.04. Just curious if anyone else has noticed this. It's not any big deal, since a refresh clears it up - just odd. (Although I wish undo's didn't take so long in camera views - it often is faster to redraw or recreate an item than wait for the undo to work...)
