...But not other grid view KCMs that are scrollable?

Comment 2 Nate Graham 2022-02-11 17:15:11 UTC

Is the active item low down in the list?

On my system, only the KCMS mentioned above are affected.

yes. 

This bug is not consistent. Sometimes I can reproduce with the provided steps, sometimes the bug only occurs when I launch the KCMs via kickoff, sometimes I need to repeat the steps a few times. lol
The attached videos show the bug happening with Cursors and Application Style KCMs launched via kickoff. Notice that the selected theme is entirely visible even when I scroll the list up. Therefore, the scrolling down on opening is unnecessary.

Application Style KCM

In that case it isn't a generic issue and the problem is specific to the code in only those KCMs. Would you mind filing new bug reports, one per KCM? I appreciate it!
