Layout Redraw and cursor behavior with Windows 7's display settings at "medium"
Operating system version
Windows 7 SP1 and up
Description of the issue
If the user's Windows Display setting gets changed from "smaller (100%)" to Medium (125% default)", Filemaker has issues with screen refresh and cursor behavior. The problem goes away in Filemaker if it's window is zoomed to 150 or greater. The screen refresh manifests as jumbled pixels if the user scrolls through the layout by dragging the scrollbar or through a list view by scrolling with the scroll wheel. (scrolling by clicking in the scroll bar track does NOT cause the issue). The cursor behavior manifests as the cursor displaying approximately 3 characters away from there the user clicks or is typing. These two issues appeared on two separate systems so they may be unrelated but in both instances switching the user's Windows display settings to "smaller (100%)" resolved the problem. I would consider this a work around rather than a complete solution.
Steps to reproduce the problem
Set Windows display setting (control panel) to at least "medium (125%)"
normal cursor behavior and clean screen refreshing during scrolls
cursor displays about 3 characters to the left of where text is showing up OR scrolling through a layout by dragging the scrollbar jumbles the pixels (both list view and form view)

Appears to be only version 13 and only Windows 7 SP 1 or greater
Reduce Windows display setting to "Smaller (100%)"
