When you do this does one of your screens shimmer?
I do but only very seldom on the secondary screen, mostly when I have
something with a bright background (say a blank document in OpenOffice).
But since my secondary screen is pretty much exclusively used for
console work (white on black) it doesn't really bother me.
Mmm, do we think this is a hardware problem, or a software bug? It
doesn't happen to you when you play a video? What resolutions are you
using? I notice it's less pronounced with lower resolutions and
frequencies? It doesn't happen to me with just a blank white screen,
only with video or animated websites and it's not ideal.
So is there a way to restrict one application to only one physical screen?
Sorry, don't know, with video overlay you can control which screen it
works on with
Option "OverlayOnCRTC2" "true"
in your xorg.conf despite this quote from the RADEON driver man page
"the option OverlayOnCRTC2 has been replaced by the Xv attribute
XV_SWITCHCRT; the overlay can be switched to CRT1 or CRT2 on the fly in
clone mode"
I'm not using clone mode - my desktop is extended over both screens. My
overlay seems to go over both screens. I'll try it anyway.
I wouldn't bother, I was just pointing out that overlay got treated
differently by the driver, but wine won't be using overlay.
Are you using the Option "MergedXinerama", it defaults to on, try
disabling or enabling it.
It seems other people have similar problems

Here's my device section for MergedFB, it may be that you have to go
back to genuine xinerama, I can post my working xorg.conf for that if
you'd like.
