Description empire 2015-11-28 17:58:34 UTC

When composition is off sometimes after some hours the main panel stops drawing (updating/animating etc) completely.  The whole panel graphic stays frozen in time (e.g. the clock is stuck and doesn't get updated, or the task bar icons are the same despite that you have opened or closed some windows). Regardless though the clicks of the mouse go through to the elements in the panel despite that they don't get displayed.

Reproducible: Always

Steps to Reproduce:
1. startup plasma desktop
2. turn off composition
3. wait some time (hours? minutes? I don't know how many).
4. turn on composition
5. open some windows so the task bar icons get updated
6. turn off composition

Actual Results:  
The panel shows the old state without the new icons and especially shows an old time in the systray and the whole panel is "frozen" in time.

Expected Results:  
panel should draw and animate everything correctly.

does clicking on anything work?

Comment 2 empire 2015-12-02 21:51:45 UTC

As I stated in my original post, yes it does. It seems that the elements (icons, widgets) are in fact there but they are not being shown or getting drawn.

Anyone can do something about this highly annoying bug? the whole panel and it's icons are now *useless* as they never refresh/redraw.

Comment 4 Szczepan Hołyszewski 2016-03-29 03:35:48 UTC

Confirming this. I am developing android apps using the Android SDK's android emulator, and the emulator turns off compositing when run. The latter only started happening after upgrading to Plasma 5.6, but it makes this older bug manifest on my machine.

I have this problem too...

Comment 6 Philipp 2016-08-02 16:18:30 UTC

Confirming this bug as well. Same procedure: If compositor is switched off (for example to watch a video without the nasty tearing that is caused by the compositor) then the panel (all panels? not sure, because my desktop only has one currently) at some point stops redrawing. Turning the compositor back on again instantly refreshes the panel and now it refreshes on every action as necessary.

What additional information do you need? Maybe I can catch a trace or help otherwise.
