Screen recording of the bug

I have a pinned Virtualbox icon in my Icons-Only task Manager.

When I click on it, Virtualbox launches but creates a new button for all of its windows. the new button has a different icon, depending on how may windows are open.

Screen recording attached. The issue reminds me a bit of https://bugs.kde.org/show_bug.cgi?id=393787

This behavior is new to Kubuntu 18.04 with Virtualbox 5.2.10. I did not see it with the older version of Virtualbox bundled with Kubuntu 17.10. I was using the same Plasma version in both Ubuntu versions.

Comment 6 Eike Hein 2018-05-23 13:30:03 UTC

Thanks.

This is an application bug. The WM_CLASS for the two windows is "VirtualBox Manager" and "VirtualBox Machine" respectively, which doesn't match the .desktop file name (virtualbox). The .desktop file also doesn't contain a StartupWMClass key that maps to either. The executables names in the process command line also don't map to the Exec= key of the .desktop file.

This should be reported to VirtualBox upstream because it's just plain super broken.

In the meantime, we can add hack-around mappings to taskmanagerrulesrc:

Comment 7 Eike Hein 2018-05-23 13:31:48 UTC

https://www.virtualbox.org/ticket/12534 claims this should be fixed, but we can still add the mappings if people still use versions where this is a problem.

Comment 8 Eike Hein 2018-05-23 13:36:53 UTC

It's still the same in the VirtualBox packaged in Fedora 28. The alleged fix is six months old though and I don't know their release cycle.
