ZDoom

This happens for all of the 4x3 resolutions (some are worse than others, though).

Reason being is that "Use traditional doom map colors" is too long of a name, thus shoving part of the sliders for brightness and screen size right off the screen. Needs to be changed back to "standard map colors" like it was before.

So one whiner and his pedantism caused a needless bug...
Figures.

Why not dump the 'use', and/or replace 'traditional' with 'standard'?

I say drop "traditional"

Oh, stop whining. It was a good change, now it just needs to be refined, is all.

it should be "Standard Automap Colours"

4x3? If you used that then you wouldn't be able to see much other than 12 pixels

Its a ratio not a resolution

it should be "Standard Automap Colours"

Except when you use it in Heretic or Hexen (probably Strife too), it's not the standard automap colo(u)rs.

Yes, so theres a problem in that.....

This is more of a nitpick than anything

Possible solution:

Name the option "map colors"
with the options becoming: "Traditional Doom" and "custom"

and "ZDoom Default"?
I always like the option to revert back to default on these sort of things.

Fixed.
