SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***


STEPS TO REPRODUCE
1. Open, say, 35 xterm (or whatever, but that's my use case) windows.  In my case, I have 6 virtual desktops, with the windows distributed in various ways among them.
2. Set Appearance/Show small window previews when hovering over Tasks
3. Hover over the XTerm task in the task manager

OBSERVED RESULT

I have a 4K screen, but only maybe a dozen or so of the previews show up in the horizontal list at the bottom of the screen.  There's no way to scroll left and right, so if there's a minimized one somewhere, I have no easy way to find it.  That strip of previews pops down rather quickly, in any event.

EXPECTED RESULT

Some kind of scrollable strip that I can search through to find the window I want, and perhaps also an option to limit the size of the previews, although they are useful.

Yes, this is a rather cluttered way of working, but it's how I like to work...

ADDITIONAL INFORMATION

If you position the mouse over one of them and hold down wither the Shift or Alt key and then scroll, does the list scroll?

Comment 2 rlk 2023-04-22 15:21:07 UTC

Shift doesn't work, but alt does (and there's also a scrollbar, which I somehow missed).

Comment 3 rlk 2023-04-22 15:22:53 UTC

Note that they're not sorted in any obvious order (by number, or by desktop).

Comment 4 Nate Graham 2023-04-24 16:54:27 UTC

Ok, so the real problem here is that a vertical scroll doesn't scroll the view when it's only horizontally scrollable, which makes this bug report a duplicate of Bug 448504.

If you'd like to follow up on other things, such as the order not being clear, please submit additional bug reports. I believe windows are supported to be order by the order with which they were opened FWIW.
