When adjusting the size of a Dead Pixel Fixer window at the center of the image, it changes as normal.
When adjusting the size of a Dead Pixel Fixer window at (at least) the bottom left corner, the sizing is extremely sensitive and causes a CTD if not careful.
Steps to reproduce
Create a new timeline
Add any media (A generator, made into a compound clip is enough)
Go to Color
Add Dead pixel Fixer OFX
Make a window near the bottom left
Change size in the OFX settings
Watch exponential change in size
