desktop ui is blinking

hi,
my desktop is blinking, at the top of the screen a white line appears from time to time , this since last update , is there way to identify the culprit ?
i’m using openSUSE 13.1 , kde 4.12.1 , radeon driver (amd hd 4850 GC) with kernel as follows

# uname -r
3.13.0-1.g4b6e17a-desktop

thanks :wink:

anyone that could help ? maybe linked with radeon (?)

Sounds like a video issue. What to tell us a bit more?

What else would you like to know ?
I have an amd graphics card (hd 4850) , using radeon.

Did you have a kernel/video driver update?

yes indeed for the kernel, i’m now with

 uname -a 
Linux linux-opensuse131 3.13.0-1.g4b6e17a-desktop #1 SMP PREEMPT Wed Jan 22 17:02:23 UTC 2014 (4b6e17a) i686 i686 i386 GNU/Linux

hi ,
anymore ideas ?
thanks :wink:

Have you tried the propritary driver?

i’m afraid that the proprietary driver is not able to manage my old graphics card, is it ? (
Radeon HD 4850 )


# lspci  |grep VGA
08:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV770 [Radeon HD 4850]

shall i update xf86-video-ati ? from where ? i’ve tried but it tries to add the one i have.
