After the installation of the updates and a preupgrade from 17.04 to 17.10, the following bug appeared, which was shown in the menu after the installation according to a dashed line, a photo as a proof of this I added as an attachment. Solved I have only temporary problem in which I changed under styles from breeze to breeze Dark and then changed back to Breeze (standard)
This was an upgrade from Kubuntu 17.04 to 17.10? Looks like the attachment didn't come through. Can you try attaching it again?
Created attachment 108360 [details] after installing all updates So my menu currently looks after the installation of all updates. Temporary I can fix the problem but that is not synonymous solution on permanence. So I reported the bug
Yes it is from the Kubuntu 17.04 after 17.10 in the preupgrade, sorry I had forgotten with.
Reassigning to plasma but I'd rather suspect some Graphics driver issue.
No longer waiting for info. :) Kubuntu 17.10 Beta uses Plasma 5.10.2.
Indeed an OpenGL driver issue.
