sudden change in app window backgrounds ... help

[William W. Austin]

A couple of days ago I used dnf to do a mass update (as in "dnf
update<RETURN>")

I am running the KDE desktop/Plasma work-space on a system which boots
in multi-user (non graphical) mode and has i&The updates appeared to go
smoothly and there were no error messages.  However, the update added a
newer kernel (I went from kernel-4.9.12-200.fc25.x86_64 to
kernel-4.9.13-200.fc25.x86_64) so I did a reboot.  (This is my normal
approach and one I've done hundreds of times over at least a decade.)

However, when the system came back up, everything looked OK until I
started to run LibreOffice (writer, calc - it's tax time...) essentially
the background for everything except the
document/spreadsheet I'm working on has gone from something off-white to
what I would get if I went into systemsettings5 and selected "Breeze
Dark" as my overall work-space theme (which I haven't actually ever tried).

Now in case you find it useful, the system has an Intel i7-5930K CPU (6
phys cores), 32 GB ram, just under 20TB disk space, 152GB swap (actually
needed), and is currently running the 4.9.13-200.x86_64 kernel, Samsung
22" monitor 1920x1200 (new monitor not here yet... sigh).

Since I hadn't reconfigured anything, I assumed that some configuration
param was changed in the update, so I  ran systemsettings5 to see what I
needed to change.  But I found nothing that helped the problem.  Along
the say I discovered that the same thing hits a few other apps as well,

Now I have another (slightly older, slightly smaller) box which
previously had the same config params as this one, so I brought up the
KDE settings until on both boxes and did a sight-verify to compare the
two.  So far as I can tell they are identical.

I did several hours of RTFM, online searches, more doc reading, more
than a little experimentation, and still have not found a solution. 

If ANYBODY can shed some light on how to fix this I would really
appreciate it.  (It bugs me the most in LibreOffice since the background
makes some of the icons almost invisible.

You could try searching for rpmsave files, since it sounds like
the old configuration was replaced, and the old one would be there as
backup.

Look in /var/log/dnf.rpm.log-[date] to see what was actually updated,
and look for likely packages that could have caused this change.  If
there is one, go to koji, and get the earlier version, and downgrade the
package to see if it fixes things.

You might want to post this on the Fedora KDE list (kde(a)lists.fedoraproject.org)
rather than here. It could be related to recent updates to Plasma.

Let me second what POC has said about posting in the KDE users list. 
There are KDE users there that aren't active here.

That being said.  I run KDE with the latest "testing" release of plasma
5.9.3-1/-2 and not seeing any issues as you've described.

Since this is a "visual" problem I would have also mentioned what video
card and driver is in use.

I would also create a second, test user, on the system and see if the
problem is evident with that user just to try and rule out user-specific
setting that may be getting in the way.
