Arch Linux

Hi,

I did a general update today, and since then I have screen problems (in KDE5/Qt environment): window borders are blinking; when I open menus, they suddenly close after a short time, and so on; the terminal cursor (Konsole) also is randomly blinking. After some research (I tried to delete configuration files and so on...) it finally seems that the problem comes from akonadi. If I start akonadi (akonadictl start) AND I give the password for the GPG key, the screen problems start. When I stop akonadi (akonadictl stop), the problems stop.

Note that it seems that the problem doesn't happen with only akonadi active, but when I also enter the GPG password. It can happen even if I don't launch kontact. But I'm not sure this is relevant.

With this problem, the system is quite unusable in conjunction with akonadi. I can't open any menu for more than a half second, which is the main problem. Note that the problems not only happen on KDE/Qt applications, but also GTK (I can't decently open the Firefox bookmarks menu).

Additional info:
- concerned package (?): akonadi-16.08.2-1
- OS: Archlinux x86_64, plasma5 + KF5, completely up-to-date
- MB: Asus P8Z77-VLE, with Intel i5-3570, 8GB Corsair RAM

Steps to reproduce:
- turn on the desktop
- use akonadi/launch kontact and enter the GPG password when asked

Steps to stop:
- turn off akonadi

I'm available to give any other relevant information.

Regards,

RK
