Yes, it appears to be the same bug.

I set "allow auto-negotiation".  Then "Apply" was no longer grayed out.  I
changed the MTU to 1471 and clicked "Apply" (and was prompted for root
password).  Checking the connection file in
"/etc/NetworkManager/system-connection", the MTU information had changed to
1471.

I was then prompted for the "kdewallet" key.  I'm not sure what that is about,
since this is a wired connection.

I closed the connection editor.  Then I restarted it.  I could see that "allow
auto-negotiation" was still checked.  I changed the MTU back to 1472.  And that
caused "Apply" to no longer be grayed out.  And I was able to save those
changes.

Tumbleweed upgrade plasma-nm to version 5.10.1 today.  So I decided to retest.

The problem is still there.  But I paid closer attention to what is happening.

When I start editing the Wired connect settings, I see "Okay", "Apply" and
"Cancel" buttons near the bottom of the screen.  But the "Apply" is grayed out,
so cannot be used.

When I change something (I tried changing the MTU from 1472 to 1471), the
"Apply" remains greyed out.  So the applet is not recognizing that there are
changes that need to be saved.

By contrast, if I edit a "WiFi" connection settings, then the change of MTU
from 1472 to 1471 (and then back to 1472) makes the Apply button active (not
grayed out).

In openSUSE Tumbleweed, NetworkManager shows up as version 1.6.2.

On KaOS, where I also see this problem, NetworkManager appears to be version
1.8.0.

I am seeing the problem on openSUSE Tumbleweed (plasma-nm 5.10.0 -- actually
called "plasma-nm5 there).

I am also seeing the problem on KaOS, with plasma-nm 5.9.5.1

With the way that openSUSE handles NM, there should have been a polkit window
that popped up when I tried to save the changes.  But there was no such polkit
popup.  Similarly, with KaOS, there was no polkit popup.

It's a while since I last used Fedora. But I seem to recall that it was more
generous with allowing network config changes, so perhaps it would not have
required a polkit query.

I'm not able to reproduce this problem. If I change MTU to any value and click
on apply, then checking the result it will be changed to the value I set.
