Slider display - 1 full and 1 partial (next) image

Hello! I’m trying to create a slider using Bricks that will show one main image and a small part of the next image to slide in.

I have used the following settings in Options:
Type – Loop (also tried slide)
Items to show - 1.2
Items to scroll – 1 (I have also tried 1.2, neither works well)

The slides look great, but the script that creates the movement becomes very glitchy. It works OK for a few slides, but then slides either skip a few images or jump back to the start before the last slide.

Of course, if I put the ‘Items to show’ setting back to a whole number, everything is fine.

Ideally, I would love to use the Bricks slider to achieve the above. Does anyone have an idea about how I can make it work?

Many thanks in advance!
