[Lazarus] Multithreadprocs and breaking out of loop

[Juha Manninen (gmail)]

I just checked your code. Indeed, I think that SetWindowOrg is somehow
badly affecting the ClipRect.

But, on the other hand, are you aware that you can make your drawing
without any use of the ClipRect? You just need to draw everything to a
TBitmap and then copy the bitmap in one quick step to the screen.

Using a TCustomControl descendent instead of a TGraphicControl will
probably also help.

It would be good if you could add this to the bug tracker and upload
there the test app as well.

thanks,
