Secondary monitor doesn't save background images.

Hi,
I use my ultra-wide Philips monitor as a main display and the 14' macbook m1 pro as the secondary one. The problem is that every time I boot my laptop the secondary monitor lose its background. link to an explaining video attached.

Hi there, this is an interesting issue. Background displays should be tied to a specific display configuration which is managed by macOS so the app has no control over what is happening. If the background display keeps reverting (even after you change it to the desired setting the second time) then either display IDs keep changing (this usually happens with DisplayLink devices) or the windowserver needs a reset. #190

I'd need to know more about the specific configuration for more. You can copy here the console logs of BetterDummy as that contains all the IDs and should show us what is happening/changing upon reconfigurations. #445

I tried to reset but it still has the same problem

I am afraid I don't know why the display background is not remembered correctly. Does the same happen with built-in/factory backgrounds?

Same issue...

This morning also the primary one loses the background image... so strange...

I have the same issue. My dell monitor switches to default background every time I put my Mac to sleep. And all windows are moved from display to MacBook

Maybe I got the problem here. I'm using a program in order to darken the menu bar and it does creating a background from the previous one and making a black line under the manu bar.
I'm investigating
