How to stop maximise when dragging window to another screen?
cn flag

I have a small (1600x900) screen and a large (3440x1440) screen on kubuntu 20.04. If I have a window maximised on the small screen and drag it to the large one, it maximises to entirely fill the large screen. Being a 36" ultra-wide monitor, it's quite annoying! Is there any way to stop this? I've got all the edge effects disabled.
