Steps to reproduce

Build gvim with

./configure --with-features=tiny
make -j$(nproc)
src/vim -g

Resizing the window just a single position will jump it back into place. Not sure why tiny build affects this.

./configure --with-features=normal is not affected.
./configure --with-features=huge is not affected.

(Very annoyingly some desktops remember position of windows - so be sure you are not tricked by it remembering fullscreen)

Expected behaviour

Starting with commandline and cursor visible.
