>Description:

I just updated my machine to -current (both base + pkgsrc) as of yesterday.
I am using xfce (in case it matters). When a window looses keyboard focus,
the mouse cursor display garbage. Here is a part of a screen photo (a 
screendump "fixes" the problem before grabbing the content, so I could not 
use that): http://www.netbsd.org/~martin/bogus_hair_cursor.jpg

The "bar code" hovering over the rxvt window should be the small hair cursor.
As soon as I move the pointer outside the window (so the cursor shape is 
reset) everything is fine again.

The only unusual settings I have in xorg.conf:

Section "Extensions"
       Option "DAMAGE" "disable"
       Option "Composite" "disable"
EndSection

 Commenting those lines out does not make a difference.

 Downgrading xsrc and src/external/mit/xorg to -D20130623 fixes the problem.

 If that works, I can send an alternate patch (suggested by upstream,
 but I wanted to wait for integration there first).

 Log Message:
 Apply suggested patch from Alan Coopersmith:

 XRRGetProviderInfo returned bad associated_capability list in 64-bit

 Unlike most of the values returned by this function, which are arrays
 of XIDs (long int), associated_capability is defined as an array of
 unsigned int.   _XRead32 reads 32-bit values from the wire protocol
 and writes them to the provided buffer as an array of long ints, even
 if that means expanding them from 32-bit to 64-bit.   Doing that for
 associated_capability resulted in a garbage value between each actual
 value, and overflowing the provided buffer into the space for the
 provider name (which is written later and would overwrite the overflowed
 data).

 Created xhiv libXrandr/XRRGetProviderInfo test case to test & confirm.

 Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com>

 Fixes PR 47979, reported and fix tested by martin@
