Serious drawing/flushing bug?

[Ludovic Marcotte]

Hi,

In the past days, I've finalized my patch for the blinking cursor/caret
support into NSTextView. It now works perfectly. However, I think there's
a serious drawing (or flushing) bug in GNUstep gui (or xgps).

For example, when calling, NSView: -setNeedsDisplayInRect, subviews don't
always receive the drawRect message when they *should* be receiving it.

If you move the mouse constantly, they always receive it.

I've created a simple program that shows the bug. It's a simple class that
extends NSView and draw a blinking rectangle every second. When you run
it, move the mouse in the window and you'll see that the drawing events
aren't propagated as they should be.

I can also provide my blinking cursor/caret patch for NSTextView that
shows the problem too.

I'll try to fix the bug into GNUstep gui (or xgps) but any hints or help
would be appreciated.

Ludo
