Why do I get pictures in the pictures when zooming?

[Pinballark]

Hi all!
My first post here.

How come I get squares from either the actual picture or from previous opened pictures?
In some zoom-size it looks as it should, but as soon as I zoom with my mousewheel I get these inside my pictures.
It happends in all pictures.
I recently downloaded the latest driver for my graphic-card (Radeon HD-4800).

It has been a problem from the start (1.5 years ago since I installed PS-4), but It has become more and more often until now when it is always.






Any suggestion or help is highly appreciated.

Wow, that's a new one.
Go to Edit|Preferences|Performance and uncheck Enable OpenGL Drawing if it's checked and see if it helps.

You can also try resetting your user preferences file.
A corrupt preferences file can cause some strange things to happen.
Why is Photoshop acting strange? Some things just aren't working right.

Hi.
Thanks.

Actually I searched the forum more in deep after my post here, and found an answer from you in a similiar post.
Tried it, and it worked fine.
I was on my way to tell that I have solved it, but you get first :-)

Thanks

this problem has happend a lot since CS4 and OpenGL Drawing, some GFX cards don't like it even though it's meant to handle it, I have to have mine turned off as well cos it's not as smoth as it's meant to be, but having it turned off is better than having it one and just got used to it not veing turned on
