I seem to have 2 similar but slightly different problems. My laptop which is never used with RD was fine on the 5.0 release until I updated it yesterday, now I'm getting corrupt title bars on it.
My home machine has always had problems since I installed 5.0. It will run fine all weekend but once I get to work and RD into it is when the problems start. The first symptom seems to be the start button stops working, then parts of the skin, especially the arrows on combo boxes start going black. When it occurred today the cpu didn't seem to go up like it has in the past. I'll say again that the problems don't happen immediately I start RD, it may be fine for several hours before going wrong.Also reconnecting RD or logging in locally wont fix the problem, I have to unload WB.
Both machines have the Dogma X4 skin. It has also happened with the non-alpha dogmax3 skin.
When running in RD the system info changes to say alpha blending isn't supported.
I hope you can shed some light on what's going on here, it's very frustrating having to keep unloading WB. I'll upload the screenshot from the laptop in a bit but will have to try and get a RD screenshot tomorrow.
