STEPS TO REPRODUCE 1. Move Cursor to the top left screen edge in the middle or right screen 2. The overview does not show OBSERVED RESULT The overview does not show EXPECTED RESULT The overview should show SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora 40 KDE Spin - Plasma 6.0.5 (available in About System) KDE Plasma Version: 6.0.5 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.1 ADDITIONAL INFORMATION I'm using Fedora 40 KDE Spin
Likely fixed in Plasma 6.1 with the new edge barrier feature, but unfortunately I don't have enough screens to be able to reproduce this screen setup so I can verify that for myself. Can you try again in Plasma 6.1? It's scheduled to be released in about a week. If you find that it's still not working there, feel free to re-open this bugzilla ticket. Thanks!
@Nate Graham: This issue persists in KDE 6.1. I have played with the edge margins but to no avail. This issue can be easily reproduced if you place two monitors side by side, but the left one half-way vertically! This also affects all corner actions monitors close to one another, as in my case i tried to set the the right corner with the same behaviour and it also doesn't work.

Confirmed, currently, kwin doesn't support registering hot corners on setups like this. It works approximately like this: - take the bounding rectangle of all outputs - register the top-left hot corner on an output that contains the top left corner of the bounding rect
