File u_02-DIX-ConfineTo-Don-t-bother-about-the-bounding-box-when-grabbing-a-shaped-window.patch of Package xorg-x11-server.28360
From: Egbert Eich <eich@freedesktop.org> Date: Fri Feb 7 09:19:45 2014 +0100 Subject: [PATCH 2/2]DIX/ConfineTo: Don't bother about the bounding box when grabbing a shaped window Patch-mainline: to be upstreamed Git-commit: 3f7cc03e47a35d05ffb3f7a6de521c41638b4c7a References: bnc#62146 Signed-off-by: Egbert Eich <eich@suse.com> Limiting the the cursor coordinates on the bounding box of a shaped window before applying ConfineTo leads to strange cursor placement when the pointer is located outside the vertial and horizontal strip of this bounding box. Ignoring the bounding box when a shape is set leads to the correct behavior.
