VirtualBox icon does not show un dock until screen locks

[Michael Thayer]

Quite simple: I start VirtualBox or a virtual machine straight from the build directory (without installing) and the icon in the dock is a red, crossed-out circle. After deliberately or due to a timeout locking the screen and unlocking it, the correct X11 property icon is shown.

Mh, I can't reproduce this with standard builds, in your setup is any .desktop file for that installed or just running the binary with no setup in well known paths?

[Michael Thayer (michael-thayer)]

No desktop files installed: everything running out of the build directory, and the only thing installed outside is the kernel modules and a udev rule.

Status changed to 'Confirmed' because the bug affects multiple users.

[Eugene Romanenko (eros2)]

Reproducible in focal fossa on all my installations (to PCs and laptop). Used virtualbox from repository (6.1.6_Ubuntu r137129). Show empty icon for running VM, until I disable/enable dock using "Extensions".

Screenshot attached.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:
* Is this reproducible?
* If so, what specific steps should we take to recreate this bug?

This will help us to find and resolve the problem.

[Eugene Romanenko (eros2)]

Sebastien, it's fully reproducible.
In focal - just "sudo apt install virtualbox-qt" from standard repo.
Create any virtual machine and run it. Issue immediately visible.

Confirmed on focal, it's also not an issue with a GNOME session in the 'overview screen launcher' so seems specific to dashtodock
