Display update problem at high magnification

When I edit text and the zoom level is 160% or greater, the display fails to update properly and any text which has shifted is overprinted. I can refresh the display, of course, with CTRL+L or by scrolling, but making complex edits is nearly impossible.  It's fine at lower zoom levels. Unfortunately, for the time being, I must  use high zoom levels in FM due to an eye injury. 

Here's what it looks like:

Changing the font and using displays with different resolutions haven't helped. I've played with the DPI compatibility settings (by right-clicking on the FM executable) to no avail. Is there anything else I can try?
