Fix artifacts on macOS with transparent windows
Due to the way macOS draws shadows for transparent windows, resizing
them will lead to text artifacts remaining present after a window has
been resized.
The `invalidateShadow` call is used whenever the opacity isn't `1.0` to
make sure these shadows are cleared before redrawing, so no artifacts
remain when resizing transparent windows.
Fixes #889.
