Tearing effects when moving windows around in Slackware64 current
I installed Slackware64 current yesterday and I'm really impressed!
The only problem I've encountered so far, is that I get a tearing effect when moving windows around on the desktop - regardless of which video driver I'm using. It didn't happen in Slackware 12.2 or Slamd64 12.2.
"lspci" shows the following about my vido card:
01:05.0 VGA compatible controller: ATI Technologies Inc RS690M [Radeon X1200 Series]
I've tried using vesa, ati, radeon and the proprietary fglrx drivers, but they all have the same tearing effect. I have also tried with KDE, XFCE and fluxbox, but the problem is there in all cases. Could it be a problem with xorg? How can I troubleshoot this?
Is this something that is unique to my setup, or are others experiencing the same problem?
