Disable shadows for transparent windows on macOS
Commit 5725f58 introduced a performance regression on macOS due to
excessive calls to the `invalidateShadow` function, however calling this
function only on redraw after a resize was performed does not fix the
underlying problem.
As a solution, window shadows are now disabled completely for all
transparent windows. This makes sure there is no performance impact,
while still solving the problem with text artifacts on resize.
Fixes #4604.
