I have tried the same under gtk1, works fine, ClipRect returns only the
rect to be updated and not the rect of the full window. Looks like a bug
in gtk2 since it works fine under windows and gtk1.
Any idea what i can do ?

I have a problem with InvalidateRect with gtk2 on linux,
Canvas.ClipRect always returns the full area and not the rect that
needs to be updated. Under windows, everything works fine.
My problem is that within a terminal emulation program i have to draw
a blinking cursor (250 ms) and blinking chars (500 ms). Under gtk2,
invalidating the area with the cursor (InvalidateRect(Handle, @rect,
FALSE)) does not work and my paint will always repaint the whole
terminal area and this causes a high cpu utilization. Under windows it
works fine and only the cursor or other invalid parts will be drawn
within paint.
Any idea what i can do under linux gtk2 ?
Thx
