Should be fixed in git HEAD now. There were two bugs (I counted so far), both were my doing, and specific to the GTK/GDK rendering. One was failing to clear the clip-region of a graphics context we then went on to use in the expose handler (the cause of the non-painting you saw where the majority of the screen was rendered in the default widget colour). The second was more subtle, and I'd swapped the X and Y coordinate conversion macros (not their inputs) when calculating the region to update on screen - so it was wrong for any case where the board was flipped, or panned away from the (0,0) origin unequally in the X and Y directions. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)
