Bug 76724

What's your arrangement? (Just paste xrandr) I tested this in a simple extended setup across a pair of monitors.

Also please verify that you have the most recent updates to that code.

If the problem persists, could you please configure with --enable-debug=full, and
compile with

diff --git a/src/sna/sna_display.c b/src/sna/sna_display.c
index 5c2781c..f78df00 100644

Vertical arrangement of the monitors seems to be a requirement for the bug to manifest.

To clarify, this is a Thinkpad X220t (SNB) with Arch Linux x86_64 3.13.7. e07f8e2 has the bug, 2.99.911 does not.

Oh, stupid bug. The bug is if the first screen is offset/transformed.

Thanks!

    sna: Only transform the temporary cursor coordinates
    
    As we need to recompute them for each CRTC, we need to reset the
    computation each time or else we screw up the coordinates and hide
    the cursors at random.
