I am using Ubuntu 18.04 with GNOME Classic. With GNOME Classic I use window list, this shows me all my currently open apps:
When I open a file in GIMP, the icon in the window list changes and appear an icon related with the image appears.
Is there a way to disable this behavior?
I want to keep the GIMP icon always.
For example, for Firefox, OpenOffice, Chrome the icons never change. It always shot the program icon, not an icon representing the page or document open.
