Weird mouse problem with KDE 4.6.3, X.org 1.10.2 and fglrx

[DeKobold]

Hi everyone,

I have a very weird mouse problem after upgrading to Xorg 1.10.2...

First of all I seemingly still used xf86-input-mouse and keyboard, so I changed to xf86-input-evdev (which was already installed anyway) to get mouse and keyboard working again.

However the problem is another one. On the KDE desktop the mouse gets stuck for a few seconds when moving in the lower right corner, more precisely one of the positions where it gets stuck is when moving out of the corner approx. 4-5 cm from the right side. This happens when I move the mouse from the corner to the left, but only if I am hat a height level from approx. 0-3 cm. It is 100% reproducible.

I already moved the taskbar? (Fensterleiste) away to the side and checked if there is a deskop effect on for the lower right, but it also happens when there is only the blank desktop.

I do not really understand what is going on, so I am open for ideas.

Hi, it is not problem with KDE. I have XFCE with this same problem, mouse freeze in lower right corner but only if I work with external full HD monitor. On built-in display works well (with lower resolution). I suppose this bug come with ati-drivers update.

For short, this option (in device section) should help.
