I just installed openSUSE 11.0, and I've noticed a very weird bug.

It only occurs in applications that use SDL to get the mouse cursor position.

If you move the scroll wheel up, and down, while moving the cursor, cursor begins to gather a delay. The cursor will move 3 seconds after you actually moved it. It'll also follow the movement you made one for one. Like the events are coming on a delay.

I've already test many SDL application, included one I coded my self to test. Games like Doom3, Quake4, and Quake Wars all appear to be effected by this. Even applications compiled for 64bit have this same problem. I'm going to try it on some other systems to see if it's not just my rig.

This is rather annoying. I'm just wondering if anyone else is getting this same problem.

It's rather easy to recreate, just move the cursor around in any SDL driven program, and while moving the cursor around, scroll up, and down with the mouse wheel. Even with just X, and xterm in the background, this problem occurs.

My system is:
openSUSE 11.0 X86_64
KDE 4
AMD Athlon X2 +3000
2 x Nvidia GeForce 7600GT SLi mode AFR, using "nvidia" driver from nvidia.com
