Hatari red side bars in fullscreen

[mig39]

Hi guys,

I've just install Hatari (via homebrew) on a 2017 iMac. Whenever I go into fullscreen, it shows these annoying red sidebars.

Anyone know how I can get rid of them, or change them to black?

See screenshot:

I don't see them on Linux. Which version of Hatari and libSDL you're using?

(I think the problem is the libSDL library used in homebrew. Mac version of libSDL has had a lot of problems / bugs during the years.)

I don't think it's the version of SDL. I'm running version 2.0.8 (which is installed as a required dependency when Hatari is installed). Hatari is version 2.1.0.

The reason I don't think this is the problem, as the red bars don't show up on either a 21.5" iMac (non-retina), nor do they show up on a 13" MacBook Air (also non-retina). In both of these cases, the bars are there, but they're black, so they're effectively invisible.

I'm wondering if there was a way to change the colours of these bars in Hatari configuration or something like that? Because it's unusable with these bright red bars burning my eyes . Or is this a problem with all retina displays?

Here's a screenshot of it running with black bars on the other computer.

Maybe SDL2 defaults to red window background instead of black on Mac retina displays. 2.0.8 is latest SDL release and I didn't see any commit after that which would have a fix for it.

If you can build your own version of Hatari, you could try whether attached change helps.

Thank you very much for your assistance.

I'll try this in a few days and report back.

I just wanted to mention this does not occur on all retina Macs. I just tried EmuTOS and TOS 1.04 on my 2016 Retina MacBook Pro and I see black bars instead of red.

I am also using SDL 2.08 and Hatari 2.1.
