  • Hi - this release of the installer doesn't update the kernel module, as 15.10 already had the required version of the driver - so it won't fix this bug.
    It's possible a later release of the installer will, or that an ubuntu update will introduce the sna/uxa workaround - it all depends on whether there's
    a suitable fix waiting in a more recent kernel, or if the bug originates elsewhere in the graphics stack, or some combination of those. I'll pass the info
    on to the Intel dev team (in case they don't know already) - for now I'd suggest you stick with the uxa/sna workaround.
