Created attachment 94111 [details]
plasma-org.kde.plasma.desktop-appletsrc

Move the panel to the left edge, resize it a bit.
After that step, the whole desktop locks up fairly regularly.

It may be the same as bug 351297, although I don't have the analogue clock in my panel.

The contents of my plasmashellrc are (plasma-org.kde.plasma.desktop-appletsrc is attached as file):

[PlasmaViews][Panel 1][Vertical768]
thickness=56

Comment 1 David Edmundson 2015-08-20 11:45:00 UTC 
just applied your plasma-org.kde.plasma.desktop-appletsrc. I'm getting the same freeze.

Thanks.
Comment 2 Kai Uwe Broulik 2015-08-20 18:47:53 UTC 
When I put a digital clock into a vertical panel and resize it a couple of times eventually it freezes here and after that the setup is broken (freezes on startup when initing the panels):

That's the BT I got after the first freeze:

That's the BT I get after starting Plasma now that it's broken:

Comment 3 David Edmundson 2015-08-21 23:14:19 UTC 
Found it.

If people can test https://git.reviewboard.kde.org/r/124874/ that'd be great.

I'll see if we can get this into the 5.4.0 release.
Comment 4 Marian Kyral 2015-08-22 05:58:51 UTC 
Hi,
I tested this and works. At least in my case, when plasmashell does not start after enabling "Show date" option.

With patch plasmashell starts correctly.

Fix lockup in digital clock

property tooSmall depends on height

If it's tool small it changes what text is shown on top of each other
Whether text is shown changes the height; super complex binding loop
that because it throws in a visibility change and goes via layouts isn't
being caught.

>From what I can tell of other code when vertical we always want to show
both bits of text.
