Hi Justin

Sorry for not following up earlier. I now tested Apper 1.0.0 on Debian
Bookworm.
I uninstalled khelpcenter and tested if the installation of ktuberling using
apper would result in the installation of khelpcenter (ktuberling recommends
khelpcenter).
It does want to install khelpcenter and I can't click it away. The dialogue
says "Zur Aufgabenerfüllung sind weitere Aktionen notwendig", so I think the
behaviour has not changed.

However, i wouldn't call the semantic issue of calling something "notwendig"
(necessary) that is not necessary, but only recommended a real bug. I would
call it a feature request to implement the apt install command line option
--no-install-recommends within apper (e.g. as a checkbox in said dialogue that
is initialized with the default).

My stakes have somewhat decreased since I haven't used apper in a long time, so
in my opinion the issue can also be closed.

[kwin] [Bug 412700] New: When closing a window in the "Show windows of all Virtual Desktops" Overview then the screen hangs for about 1 second

[Dimitri Nüscheler]

https://bugs.kde.org/show_bug.cgi?id=412700

Bug ID: 412700
   Summary: When closing a window in the "Show windows of all
Virtual Desktops" Overview then the screen hangs for
about 1 second
   Product: kwin
   Version: 5.12.8
  Platform: Kubuntu Packages
OS: Linux
Status: REPORTED
  Severity: normal
  Priority: NOR
 Component: compositing
  Assignee: kwin-bugs-n...@kde.org
  Reporter: dimitri.nuesche...@sunrise.ch
  Target Milestone: ---

SUMMARY
When closing a window (or when hovering the mouse over 2 windows and the
desktop in the background) in the "Show windows of all Virtual Desktops"
Overview (Ctrl+F10), then rendering stops for one second. After about one
second the rendering continues at a normal framerate.

STEPS TO REPRODUCE
1. Open 2 windows (Maybe it shows even with one window). For instance 2
konsole-Terminals.
2. Press Ctrl+F10 in order to activate the "Show windows of all Virtual
Desktops" Overview.
3. Close one terminal window

OBSERVED RESULT
After closing the window, the screen content hangs for one second. The mouse
cursor movement is still rendered at proper speed. The hang occurs at the time
when the window is fading out as a result of the close action, but it doesn't
seem to be related to the exact state of the rendering.

My setup uses 2 monitors, but it is also possible to see the hang if only one
monitor is used.

With 2 monitors, however, it is possible to produce a hang by hovering the
mouse between 2 windows that are on different monitors. It is necessary to move
the mouse between the 2 windows and to hover also a piece of the desktop region
in order for the hang to show. It doesn't work when the 2 windows are on the
same monitor.

EXPECTED RESULT
Average framerate above 50 frames per second. Longest interval to be smaller
than 40 milliseconds.
