Description of problem:
Please see bug report at:
When using intel driver, I see graphical artifacts when highlighting text in Spyder (until Spyder redraws the area due to integrated word highlighter several seconds later). I don't see this issue when using vesa driver.
My graphics card is:

I have seen the same issue on a different hardware with (I suppose different) intel video card, but I don't have its lspci now.
An important fact is that everything worked when I booted Fedora 15 from Live CD. Something must have got broken since then.
I don't really know whether this is a intel driver issue, or some QT issue. I hope you can guide me.

Steps to Reproduce:
1. Run Spyder
2. highlight words by double clicking on dragging the cursor (see the video)
graphical glitches only on intel driver
no graphical glitches

screencast of the issue
Looking at the video, I would tend to believe that the investigation should start from the top, and that means probably the text editor component used by Spyder. Reassigning in the appropriate direction.
can reproduce on my f15 box with old i945.
my f14 box with i965 seems ok.
sounds like a fun one to debug what's going wrong.
don't see anything similar, in other PyQt4-using projects either (like eric or marave).
I'm tempted to bounce this back to spyder for now, there is some latent display/render glitch/bug.
This is fixed in F16 and most recent spyder version. Close if appropriate.
Thanks for retesting it. Closing the bug as CURRENTRELEASE.
