Starting with 5.15.11 Qt returns a diverging screen size which leads to cut off elements that are attached to the botton of the screen.

Using the default 10" Emulator returns

E libandroid_x86_64.so: QSize(1280, 728)

for Qt 5.15.10 and

E libandroid_x86_64.so: QSize(1280, 752)

for Qt 5.15.11.

Reverting qtbase/2989451 seems to bring back the original behaviour.
