I am running the stable Gutsy 7.10 as well and have this same issue. I have a Toshiba Satellite A105 with the Intel 945 chipset.
If I turn the affects off and then on again it seems to resolve the issue for me as well.
I still haven't figured out how to get the login screen problems resolved though. The options on the login screen are almost unusable because I have to scroll through several screens to get to where I want.

I hope this is fixed soon.
