Description Joshua Moss 2017-10-15 23:01:48 UTC 
This was mentioned by another person in the forum on this link:  https://discourse.libsdl.org/t/sdl-fullscreen-toggle-shrinks-window/23160/2

This is a relatively new bug that was introduced since 2.0.6 as it did not occur in 2.0.5 and below.  Whenever you switch from desktop fullscreen (borderless) to windowed; window shrinks by a certain amount.  Keeps shrinking each time you do it.  I have a feeling it has something to do with some new hints that were added for logical size rendering.

Current workaround is to keep the previous window size intact (by storing values in variables) before going into fullscreen.

This should be fixed in the SDL 2.0.7 RC build:

Can you confirm?

Yep, it's completely fixed now.  No more need to workaround. ;)
