Toggling "Full animation" first glitches, then reduces vertical size

[tomstorey]

Version of OpenTTD

1.9.3

Expected result

None

Actual result

The first time "Full animation" is toggled (on to off), the vertical screen size reduces slightly and the top of the screen (ala menu bar) is duplicated.

Subsequently, each time "Full animation" is toggled on and off, the veritcal screen size is reduced slightly, this can be done until the game is an unplayable slither on the screen.

Exiting and then re-entering full screen restores the full vertical size again.

Steps to reproduce

On Mac OS X, open game and go to full screen. Toggle "Full animation" repeatedly.

Got a repro of this. 10.0 official binary. macOS 10.15.1 Catalina.

Happens in full-screen mode only. Cannot repro in windowed mode.

There was a previous incidence of this bug which was visible in windowed mode. I haven't looked yet if/how that was fixed, but I haven't seen that one happen for quite some time

I wasn't able to repro in windowed mode either. Unfortunately I wasn't able to test 1.10.0 as it's not starting on my Mac (crash on start).
