Mouse leaves trails on the screen.
Not when I'm moving it around, just when I scroll windows, it's like the mouse doesn't get redrawnm so I'm left with a trail of pointers on the screen. Also, when I click on a dropdown menu, the mouse is usually surrounded with a box of what it was on before (like if I'm on the desktop and click a dropdown, I get the box but the pointer still has a box that looks like the desktop around it).
I'm on slackware 10, with dropline-gnome 2.6, using xorg.conf. My vid card is an ATI Radeon 9500, and I'm using the latest driver off of their site. If it matters, the mouse a Microsoft Intellimouse Explorer.
