Running Leap 42.1 64 bit on the setup listed below. Install is clean on new system.

Have intermittent problem with monitor screen rapidly flashing in intensity. Using the on-board graphics package on the motherboard. Problem occurs on all software and all screens. Always after running for a few hours. Don't know if the problem is heat or software incompatibility or something else.

Any suggestions on dealing with the issue would be appreciated.

CPU: AMD FX 8320 eight core
Chipset: AMD 760G (780L)/SB710
Ram: 8X2=16 ddr3 gigs
Graphics: Integrated ATI Radeon HD 3000 GPU

Hi,

Do you by any chance use the desktop effects? I've seen this happen before when the desktop effects crashes. Restarting the X-server fixes your issue then. If you're using the nouveau driver, you may want to try the proprietary AtI driver to fix your issue.
