Good to know, thanks!

I can also confirm that after applying the patch, the freeze no longer occurs
on my system.

The Plasmashell freeze seems to only occur when the Pie Chart display style is
set. There are two lines that often appear in the system journal relating to
the Pie Chart when adding the widget. 
> plasmashell[1794]:

>  QML FullRepresentation: Binding loop detected for property "implicitHeight"

These lines also appear during the X11 session, where there is no freeze. So
the only other errors that stand out to me are these Wayland errors. Not sure
if they are related.

Hmm, if I add a System Monitor widget such as Total CPU Use to the panel in the
Wayland session, then click on it, the freeze occurs. If I log out and log into
the X11 session, then click the widget, it works and appears normally, no
freezes. But, if I then log out of the X11 session and back into the Wayland
session, then click the widget, it now works normally and there is no freeze.
It will also continue to work after rebooting. However, if I remove the widget,
add it back while in the Wayland session then click on it, the freeze will
occur again.

[kwin] [Bug 480171] With 225% scale on a 4k screen, right-side-tiled windows and full-screen video/image content are not fully adjacent to right screen edge

Yes, I think that particular bug has been fixed in Plasma 6 as I no longer see
2561x1440 being reported by the games running in XWayland, when using 150%
scaling.

Forgot to mention that I am running Wayland.

I have a monitor with a resolution of 2560 x 1440. When I use Plasma 6 with
150% scaling, I see the distracting line on the right side of the screen. On
Plasma 5.27, there was no line but some applications and games would report the
maximum resolution as 2561x1440. I did have to lower the game resolution to
2560x1440 as it did cause some graphical issues within the game. Now on Plasma
6, every game I have tested reports a maximum of 2560 x 1440 and works
normally. But the line is present everywhere.

One thing I tried was installing the colour profile for my monitor, provided by
the manufacturer. The line does disappear when using the profile. Though I
think it may only be hiding the issue.

I recently started experiencing this issue on Plasma 6.0.3 and 6.0.4 on Arch
Linux, but with the Total CPU Use and Memory Usage widgets when added to the
panel. All I had to do was simply add them to the panel, exit edit mode, then
click the widgets for the freeze to occur. Also in most cases, there would be
no pop up and Plasmashell would simply freeze until the process is killed.

This issue occurred on my second PC with fresh installations of Arch Linux,
with the Plasma versions mentioned above. I was also able to reproduce this in
a virtual machine (on different hardware) using virt-manager, with Virtio and
3D Acceleration enabled, on both Arch and the latest KDE Neon User Edition.

I also want to note that my main desktop is also running Arch with Plasma 6.0.4
and does not have this problem. But on this machine, Plasma had been upgraded
from 5.27. So this issue mainly concerns new installations.
