Description Henning 2023-02-22 15:09:24 UTC 
If you have two or more screens next to each other, and one is bigger, there is some space at the edges of the bigger screen, where you cant move your mouse pointer to the smaller one.

You have to move the pointer up/down until it reaches the area where the "border" between the two screens eist.

The result is, that you have to  sometimes drag the pointer at the edge of the screen, until it finally reaches that area and goes to the other one, which is kinda annoying.

A solution would be, to skip from every point >= the top or <= the bottom alignment of the two screens to the top or botton edge of the smaller screen.

This would only apply in the direction big-->small and not the other way around, not resulting in glitches where windows would be stretched or moved upwards rapidly, when dragged from the top of the smaller screen horizontally, where it isnt the top of the bigger screen.

It would also only apply to the pixel at the edge of the screen and not other ones.

Workaround:
align the two screens so that its least annoying to use. still not very nice solution.

Can you explain why this is a problem?

This is a wishlist entry for improvement of the experience. It has low priority.

The Problem is, that it doesnt feel like two differently sized screens, but they behave as if they had a physical barrier in between them. Having this small trick would improve usage of for example a small Laptop monitor and a big external one massively, when using small touchpads where it takes a lot of extra swiping to get the mouse to the middle.

I would really like to contribute to KDE, but its huge for me at the moment.

Thanks for the info.
