When selecting and then de-selecting on windows there is thin white line between where the top of the selection was and the acsender. Looks like the inalidation rect is one pixel too short.

Can still reproduce in Version 54.0.2824.0 dev (64-bit). Sounds like a paint invalidating issue, adjusting component accordingly.

Fixed. I can't reproduce on Linux ToT or Win 10 Canary Version 59.0.3033.1 canary SyzyASan. I believe that wkorman's fixes for text selection area fixed this issue too.
