Hello Novo,

Like I said. We need to remove IsCompositedGui() check from XCreateWindow and stay only with CWBackPixmap flag.

The bug in this place is obvious, because smooth resizing works on some machines, but on others it doesn't. So the final code should look like this:

Window w = XCreateWindow(Xdisplay, RootWindow(Xdisplay, Xscreenno),
	                         r.left, r.top, r.Width(), r.Height(),
	                         0, CopyFromParent, InputOutput, CopyFromParent,
	                         CWBitGravity|CWSaveUnder|CWOverrideRedirect|CWBackPixmap,
	                         &swa);


Sincerely,
Klugier


This fixed flickering in configuration 1.

Checked on a home computer with two rotated monitors - no flickering.

Thanks!

Regards,
Novo
