    We're using the Sandy Bridge Intel NUCs with onboard HD4000 and have noticed that when rotating the screen orientation, any movement on screen (scrolling, animation, moving windows etc) suffers from severe v-sync tearing. We've approached Intel directly and they have confirmed that there is indeed an issue with the current Linux drivers so portrait orientation is currently not supported.

    We've tested on Ubuntu Desktop 12.04 and 13.04 64-bit with and without the Intel Graphics Installer drivers from this site. Using a resolution of 1920x1080 (native monitor resolution) has no issues but at 1080x1920 the graphics tear badly. We believe it's a problem with the way the compositor (in our test case, Compiz) translates and remaps the pixel grid to emulate a rotated resolution, which means we lose our frame buffer v-sync settings.

    We've found an older article discussing a similar issue here but has no resolution:

    We've tried all sorts of advanced settings in compizconfig settings manager to no avail.

    Portrait orientations on Windows (tested on Windows 7) platforms also do not suffer this same v-sync issue.


    Has anyone else noticed this issue and/or know of a possible workaround?
