Yep, no further problems since uninstalling Docky. I guess it was a conflict
between Docky and KDE/Plasma.

Auto hide panel then makes the panel render properly again but it doesn't make
the plasma widgets start updating again.

I'm not convinced it's the same issue, compositing appears to be working fine,
I'm using Docky in 3D and even though plasma has stopped rendering Docky is
displaying perfectly, Docky normally drops back to 2D mode and complains when
compositing fails. Also the fancy 3D shadowing on application dialog boxes and
windows is still working, with compositing having dropped out I would have
expected that to all be gone. It's just the panel and plasma widgets that have
stopped rendering.

After using KDE neon for an hour with the following programs open, kdevelop,
Chrome, Skype, Dolphin ) The task panel has stopped rendering. I had the clock
show seconds and it's now frozen. If you mouse over the task manager the
adjacent programs info pops up but not the programs info that you are actually
mousing over. The desktop plasma widgets have stopped updating. So it's not
just the panel that stops updating it's the whole desktop... however the
applications themselves work normally.. clicking on panel items appears to
work, but possibly you don't get what you expect, it's just the rendering
that's frozen. I can put together a video if it's unclear as to what I'm taking
about. Never had this problem prior to the recent upgrade to KDE 5.12.2.

Even though there's no gaming involved it's still almost certainly the linked
report. Compositing could have reset for some other external reason.

We can always reopen if we get more information.

Yes, Nvidia GeForce GTX 570M running the Nvidia driver 384.111.

No, I never play any games on this machine. I had 4 instances of Dolphin open,
kdevelop, Filezilla, Gimp, kmail, maybe Discovery.

I've since rebooted and switched the panel to always visible to see if I can
get the problem back again.

This problem appeared after the recent update. Firstly to experience the
problem you need to switch OFF auto-hide on the panel. If Auto-hide is enabled
then you won't see the problem.

So you first become aware of it because clicking on running tasks in the task
manager maximises or minimises the wrong tasks. You then realise that the clock
time is frozen and not updating. You can click on items in the task manager but
it's as if the task bar is not being updated. Enabling auto-hide refreshes the
task bar and clock. Switching auto hide OFF again and the task bar then doesn't
get updated eventually. You need to open multiple applications to see the
effect.

thanks for reporting back, it was probably fixed by another bug report.
