With both CB 8.xx and 10.05, my source editor pane corrupts text frequently during scrolling.
This results in an editor pane that looks like a corrupted image, with half lines of text being repeated, etc...
Clicking the mouse in the editor pane, to double click a word, or drag-select some text, or similar action, usually causes a refresh which removes the corruption.
Research on the internet did suggest that there was a similar problem with wxWidgets at some point, but I'm reasonably sure that this didn't start happening until after I installed a new graphics card (6870).
Updating to 10.05 did not resolve the issue, neither did reinstalling the graphics drivers (Catalyst 10.10b Hotfix). I'm using a custom syntax highlighting color scheme, and Consolas (at 16 or 18 pt, IIRC), in case it matters.
Have not tested the PCs RAM, going to do that tonight, but I can only reproduce the problem with CB.
Any suggestions appreciated...
