Summary0013161: Moving mouse cursor over TScrollBar in Windows 7 and Windwos Vista causes blinking random bitmaps
DescriptionIf you create tform with tscrollbar on it and run application on Windows Seven or on Windows Vista, you'll see strange effects instead of animation during moving cursor over scrollbar: some random data is displayed for a little moment.

This data can be piece of other windows, or simply black area, or one of previous stage of the scrollbar (totally randomly).
Additional InformationFirst bug report about this error in Vista sp1 x64 I have received in december'08, but I haven't Vista and didn't create issue.

But several days ago I've seen it by own eyes in Windows 7 and decided to report it.
TagsNo tags attached.
