fix cherry picked from commit 0.4.12-dev-954-g
1f619b27814f3bbf9673754a69bcae50c89fed19
-----------
but since above commit did introduce a new regression CORE-15893
symptom "Most of maximized windows have extra row of pixels around"
I had to port back those 2 follow-up-master-commits as well:
0.4.12-dev-956-g
0197c4f875d3332dbc4656a6360e3c7e9def2ed5
and 0.4.13-dev-397-g
3cc50cedaf5e74041608d403054d1fe6394596e6
Side-note: This results in the same final state as 0.4.12rls0, because
I ported
0.4.13-dev-397-g3cc50ce into
0.4.12-RC-29-gab7f77a earlier.
