Strange Display problem with Y560

[largecow]

Hello everyone,

I've been having a rather odd display problem with certain types of video on my Y560.  It's running with an ATO Mobility Radeon 5700 series, windows 7, i7 processor, 8GB of ram.

Just yesterday I started getting a strange display error with certain types of video.  I've been getting horizontal lines and a very strong flicker.  It seems to happen when flash is running, with certain websites like homestarrunner.com, gmail when a theme is turned on, or with many game intro screens.  3d seems to be fine.

Opening realplayer, the realplayer logo displays the problem, but when the FLV movie starts, it doesn't have the problem.

The problem seems to go away if a large window is in the foreground and the video is in the background, however, if it is a smaller window in the foreground, the problem will spread to that window.  If I move the smaller window to the left side of the animation, the problem will stop affecting both the window and the video, but as I move the smaller window over the video and to the right of the screen the problem will affect both.

Taking a screenshot results in a normal image without the problem.

As far as I can tell there have been no major software changes to the system, and  the temperatures are hovering around 50 degrees.  I just opened up the laptop to clean out the dust.

I'm stumped. Any ideas?

Hi Cow,

please try right click in to the Adobe flash player window... select Settings... un-check Enable hardware acceleration.

Thanks for the quick reply,

Disabling hardware acceleration in flash doesn't seem to help.

Further details: the problem seems more severe with Chrome than with Opera for some reason, and seems to be worse with dark colours.

Hi Cow,

Chrome has its own integrated flash player, don't know about Opera...

I once experienced this bitchy behavior with Adobe flash player plugin using Firefox

and disabling hardware acceleration fixed it for me.

Can you test how flash video behaves using IE or Firefox.

Hey, thanks again for the quick reply.  I appreciate it.

IE has the same problem, but again, not as pronounced as in chrome.

I get the same problem with Steam, both on the main page and with various games I run.  Again, once it gets to a 3d section it's usually ok, but opening cutscenes and intros seem to be severely affected.

I guess the next step would be to try uninstalling flash and re-installing, and then the drivers.  I hope it's not a hardware issue.

If it just started happening yesterday, have you tried system restore or maybe uninstalling chrome and re-installing?

tried system restore, no luck.  I'll try reinstalling chrome
