Why does gzdoom list multiple identical resolutions?

[invictius]

E.g 1280 and 1920 are each listed three times - are they actually 8, 16 and 32 bit colour modes or something?

To be honest, I never checked what is happening here. That code was inherited as-is from ZDoomGL, it's probably some bug in there.

I saw that bug in Chocolate-Setup. It uses SDL to detect the screen resolution. It may have something to do with the graphics driver not being installed.

I don't think that's the case, it's happened on every video card I've owned since 2009.

Have you installed your manufacturer's driver for each cards?

It has nothing to do with the drivers, you can stop that.

^ If you're sure it's a bug in the code, then that's fine. Every time a saw a bug like this was because of the drivers.

It's not because of drivers. I get the same thing, and I know for sure that I have my drivers installed. It's been happening for a while now too.

I had a look today, it was just a stupid bug in the function that collected the resolutions. As I said, I didn't write it myself, so I have no idea where the idea came from, but it just assumed that identical resolutions are sorted by display frequency in ascending order. But that's not the case - on my system it often had 60 Hz first and 59 Hz second, no idea what the point is - and these duplicates were not filtered out.

Will be fixed in the next dev build.
