STEPS TO REPRODUCE 0. In a wayland session (tested with Plasma 5.26) 1. Start kate, minimize or hide it 2. Open kate from start menu. A window displays "Session 'x' is already opened in another Kate instance." 3. Click "Switch to instance" Another scenario 0. In a wayland session (tested with Plasma 5.26) 1. Start kate, minimize or hide it 2. Open any kate file eg "foo.txt" from start menu. OBSERVED RESULT Kate window is not visible. EXPECTED RESULT Kate window is raised to forefront.

Can reproduce. Kate *generally* has activation support because its open window raises as expected when a file is opened by Ctrl+clicking on a path in Konsole. But it seems to be missing for the specific piece of functionality.

The API we use atm is without effect.
*** Bug 430754 has been marked as a duplicate of this bug. ***
The message in the other bug stems from our use of API that no longer works.
I got the info that one shall use KWindowSystem::requestXdgActivationToken and wait for KWindowSystem::xdgActivationTokenArrived and send this over to ensure one can activate, at least for this case. If somebody has time to work that, that would be nice.
