Description dismark 2016-07-18 09:13:04 UTC

I use the latest version of Kubuntu (16.04). Very often, when i use an application (every application : Dolphin, Firefox, LibreOffice, ...) the buttons of the window disappear  (minus, window, close) . 


Reproducible: Sometimes

Steps to Reproduce:
1. Not possible : this is random
Sometimes i can use for many hours with no trouble,
other times, it appears very often




The only solution i have found is to disconnect and to connect again.
This problem appears on the two computers i use : an AMD and an i386.

I use KDE Plasma 5.5.5
version of Qt : 5.5.1
Kernel : 4.4.0-31 generic
OS : 64 bits
CPU : 2 x AMD A4-6300 with Radeon HD Graphics
Memory : 5 Go
The screen is connected in HDMI (but the problem exists also on a notebook, and the screen is not in HDMI)

When i use my computer this morning, the problem arrived very quickly,  when i used Thunderbird .  Thunderbird refused to close by : --> File --> Close. So i close my session.
As it was the beginning of the day. I thought it will be interesting to have snapshots of the different log files :  so i attach them to this response.
A strange thing : when an application like Dolphin (yesterday) had the same problem, it accepts to close by : File --> Close ... BUT in the taskbar it appears (image1)

Comment 9 dismark 2016-07-19 13:10:29 UTC

Additional information : when i restart my session, after this problem, the screen definition changes and return to the maximal definition of the screen.
I currently use 1024 * 768

Please ask for help in a forum of your distribution. The files you attached were not requested with comment #1.

Additionally, please ask for help in a forum of your distribution how to update Plasma and Qt from PPA backports. The Plasma and Qt versions you are using are outdated.

I have updated Plasma, and all seems to be correct
Like Plasma is needed by KDE, i supposed the upgrade was automatic with standard update.
Thank you for your help.
