Game console rendering errors

[clort81]

I see problems with scrolling game-console in today's build.
System:
libsdl2-2.0-0 Version: 2.0.16+dfsg1-5
aarch64, gcc-11

Possible there's some unsafe math being used to scroll that console window.

Thanks for pointing this out. I'm just starting to catch up with github issues again... Sorry. Will write a bit more when I have had a chance to look at what's going on. But unsafe math is a good guess. :-)

I tested a fresh build with flags="-O2 -march=armv8-a+crypto+crc+aes+sha2"
The same breakage occurred in the text window.
Here was console output.

If there are some things i should try toggling/changing to help narrow it down, I'd be happy to do it.
