If the pointer is also checked at the xorg side, it works as expected. Tested with the patch:

After a quick check with Snowball (Mali 400), it worked properly and as expected, so this could probably be related with the current SGX driver available for Pandaboard. How to reproduce the issue: 1) Enable https://launchpad.net/~canonical-qt5-edgers/+archive/qt5-daily 2) Install 'snowshoe-mobile' package 3) Run snowshoe: $ PATH=/opt/qt5/bin:$PATH; snowshoe This is with Ubuntu 12.04 with pvr-omap4 1.7.10.0.1.21-0ubuntu1 (from archive) and also 1.7.15.0.1.57-1 from TI's PPA.
