Bezel backgrounds and ultrawide monitor

[jaz666]

Hi folks

I've been trying for hours to figure this out, but can't find anyway forward with it, so hope someone may be able to help.

I've had a Hyperspin/Rocketlauncher setup for a few years now and everything has been set up and running smoothly. I have had the Metalzoic bezels and bezel backgrounds downloaded from the FTP and installed and working.

However, I have recently got a new ultrawide monitor and, unsurprisingly, the background bezel aspect ratio is no longer correct.

Now, I wasn't expecting the backgrounds to magically resize themselves. What I had hoped for was that the bezel backgrounds would stay at their normal ratio and I would have black borders at either side. I am perfectly happy with the borders. 

Unfortunately, what happens is the bezel backgrounds automatically stretch themselves to fill my entire screen and, as a result, the background no longer fits the actual bezel (or emulator screen).

I have been trying all the setting that I can find on RL to stop the stretch. There are plenty of settings for the actual bezels (which are correctly configured for my monitor), but nothing I can see for the bezel backgrounds.

Has anyone found a solution to this please? Any help would be much appreciated!

Cheers
