DevToys crashes when window is moved around while using Text Diff

[Bernard-Borg]

Current behavior

DevToys crashes when I open Text Diff, put text in both sides (could be with a difference or without) and move the window around.

How to reproduce it (as minimally and precisely as possible)

1. I open up DevToys
2. I go to TextDiff
3. I paste in some text in Text Diff on both sides with or without differences
4. I move the window from around
5. DevToys crashes

You can even just paste the following text on both sides:

1. I open up DevToys
2. I go to TextDiff
3. I paste in some text in Text Diff on both sides with or without differences
4. I move the window from one monitor to the other
5. DevToys crashes

Expected behavior

The window moves with it crashing
