Image jumps bigger randomly

I have an issue with an image which randomly jumps bigger / changes the sizes while previewing and also while editing. I want to build the following design in combination with an horizontal scroll animation. Does anybody have an idea to fix this?

Hi Korbis,

You can try giving the image 100% width or other styling options that won’t affect the overall outcome.

I’ts a known issue for me!

I think it worked. Thank you!
