Perhaps this is a clue. With or without your patch, every single time I
change the icon in user-manager, plasmashell immediately prints the following
to the console:
file:///usr/share/plasma/plasmoids/org.kde.plasma.kickoff/contents/ui/Header.qml:55:5:
QML Image: Error decoding: file:///var/lib/AccountsService/icons/dev:
Unsupported image format
The file exists and is a valid image:
file /var/lib/AccountsService/icons/dev
/var/lib/AccountsService/icons/dev: PNG image data, 64 x 64, 8-bit/color
RGBA, non-interlaced
xdg-open /var/lib/AccountsService/icons/dev
[opens in Gwenview]
So I think we can confirm that the icon is being changed on disk and that
plasmashell sees the changed image and tries to load it.
However without your patch the avatar changes anyway (most of the time),
while with your patch, it does almost never does until plasmashell is
restarted. It seems like there is some latent bug with QML Image
loading/parsing/MIMEtype detecting/something else that is only being triggered
when the `OpacityMask` is applied to the `Image`...
