I have missing systray icons. It happens on two computers with Debian testing (plasma 4.6.5, frameworks 5.25.0). On one computer it seemed to happen after installing hplip. See screenshot. There should be network manager, volume control and Bluetooth but I can neither see the icons nor click on them. I can not even connect to wifi. On the other computer hplip is not installed. But I have only volume control and a huge gap. Reproducible: Always Steps to Reproduce: It happens on two computers but I don't know how to create this behavior. I will test plasma 5.7 as soon it is in debian testing. But I did not find any bug that was fixed in 5.7. I saw Bug 352055, but this was already fixed in 5.6. I marked this bug as grave because this bug does not allow me to use network manager.

I updated to 5.7 from debian unstable. The bug is fixed there.
