Bug 488426

SUMMARY

It is currently not possible, solely using a tablet, to move the cursor between screens when the tablet is set to "Follow the active screen". 

The changes to the Active Screen logic in Plasma 6 (where it now follows the cursor position) means the tablet cursor is stuck on one screen, as the tablet is mapped to the boundaries of the screen and therefore the cursor cannot leave the screen to make another one active. Instead a mouse has to be used to move the cursor to another screen, which will change the target screen for the tablet.

Prior to Plasma 6, it was possible to Alt+Tab to an application on another screen to move the tablet cursor to that screen. This is no longer possible. 

Meanwhile in X11 there was a dedicated shortcut for "Toggle between all screens". To my knowledge this does not exist on Wayland.

I'm not sure what the best solution for this is, but there should be a way to switch screens without having to use another device, or manually setting the target screen in the kcm every time.
