Description
A screenshot taken of off the title screen of Saturn's game Dead or Alive (Japan), emulated through Beetle Saturn, will have a bad aspect ratio if RA's video driver is set as d3d10/d3d11/d3d12
Expected behavior
The aspect ratio scale should be respected, regardless of the video driver. When using gl video driver this issue does not happen.
Actual behavior
The titlescreen ratiot cannot possibly be correct, it squishes the image (width issue). When the video driver is set to d3d10/11/12, I will get different resolutions and aspect ratios at different places; specific examples:
RA's settings have a AR scale of 4:3, none of those screenshots seem to be at that ratio, but 2 and 3 aside, 1 (the title screen) is not right in any way.
Steps to reproduce the bug
Bisect Results
I have no clue, all I can say is that this does not happen when using Kronos emulator; this isn't to say that the issue is the emulator, but there certainly is a causality between the two. As far as I can tell, Kronos forces the video driver back to gl or glcore anyway, but not Beetle Saturn.
I have also compared this using the same method with another title, Virtua Fighter 2 (USA); in this case the AR is closer to what would be expected, emphasis on the title screen:
