ScummVM 2.0.0 text in combobox is erroneously not painted until mouse hover

0.4.9-RC-35-g3eb03ef

ScummVM 2.0.0 from rapps.

When ScummVM main app is started first time, the app asks when to do the update.

Expected result
There is a combobox that by default should display "weekly".

Observed result
"weekly" is not displayed initially and only drawn when we hover the combobox with the mouse.

Nothing is logged at the moment I hover with the mouse over it to make it draw.
