Some launchers have questionmark icon instead of normal icon

[Ján Koštial]

Hello friends,

I recently upgraded my Linux Mint 19.3 Cinnamon to version 20.
After upgrade some launchers (not all) have the question mark icon.

For example - calculator.
In the menu it has the correct icon.
When it is invoked from menu and no launcher is on dock the icon is correct.

But when I create a launcher (by drag-drop from menu or by "Make it a launcher" when it is running) then icon is falling to question mark.

Icons theme is set to Mint-X.

Screenshots in attachment.

Thank you for the bug report !

It seems that some icons now have names like "org.gnome.Calculator", and the dock is tricked by the dots.

Hello again,
which version is containing this fix?
Currently I have 3.4.1-3 from Ubuntu focal repository (Linux Mint 20.2).
But problem still exists.

BTW I cannot use your PPA.
I am getting the following error:

$ sudo add-apt-repository ppa:cairo-dock-team/ppa
[sudo] password for xuser:
Cannot add PPA: ''This PPA does not support focal''.

Hi,
I guess it's my fault, I should change the version number...

I'm sorry for the PPA; what about compiling the sources ? it's not that hard ^^

One year later and apparently the fix is not available in the Ubuntu focal repo yet (version here is still 3.4.1-3). Is there any fixed deb package available for focal anywhere?
