All software
Incorrect behaviour

The graphics viewer menu displays incorrect aspect ratios of the graphic tiles
Expected behaviour

All sprite tiles should be 1:1 pixels
Steps to reproduce

Open any game Press F4 to open the menu and printscreen any of the graphics displays
Additional details

Older versions of MAME used to display the graphics tiles 1:1 correctly, regardless of how zoomed in or out the window was. Now zooming in and out warps and stretches out the sprites.
