Default Teletext like filckering problem on Geforce 9600M GS with nvidia 190.42

After a bit of hours developing under KDE the screen starts to flicker, especially the fonts, see how the clock, menus and filenames looks in screenshots.
In dmesg I've seen:
Code:

The temperature reported from nvidia-settings was 62C and after restarting computer everything started to work like previously so I reject overheating problem. But this always happens after some time when computer is turned on. This problem with flickering only texts I experienced first time, but often I got whole screen flickering in manner that it was imposible to restart computer. In such situation I had seen only changing graphics - when I clicked somewhere some part of screen changed but not the one I clicked, and some buffered icons of applications were displayed in place they shouldn't.

Included nvidia-bug-report.log.gz was generated after the restart so in case any information about state of card at the time of failure is aquired it wouldn't be suitable.
