Rendered view not working properly in Cycles Render

Hey everyone,

I couldn’t find a post with this problem so I will post it here.
I’m getting a strange look when I want to change to Rendered. It simply won’t render and just shows a bunch of icons.



This is in ‘Rendered View’ under ‘Cycles Render.’
I’m not sure what it could be, if someone could help me out, I’d really appreciate it. Thank you.

Did you ever find out what was the problem? I have this same strange issue. It happens on fresh uninstall/reinstall of blender 2.70a, with a brand new default blend opened.

I had it working before with same version, and not sure what went wrong.

This is the error shown in the console:

Shader compile error:
Fragment shader failed to compile with the following errors:
ERROR: 0:5: ‘’ : Declaration must include a precision qualifier or the default precision must have been previously declared.

I also had this problem and found it occurred when I loaded Blender 2.70a. Returned to 2.70 and problem disappeared. Actually I have both versions loaded and can open either one. Only 2.70a has this problem.

Is this a bug, perhaps?

My graphics card is:
ati mobility radeon hd 4650 (latest drivers)

Might we all be using the same card?
