I have the problem, that after an upgrade 14.04 -> 16.04 -> 18.04 and the corresponding change of Unity -> GNOME many of my programs do not show up correctly in the list of open windows (typically on the left side).
I put an image of the problem here:
Above the icon of GIMP there is another icon that seems to be shown for a whole set of programs. Of course this is not nice as I have to hover the icon with the mouse to see what program it represents using the tool tips or the right-click menu. In this example the program is a KDE program (I like kile much more for TeX-writing than any other program I am aware of). In recent versions of ubuntu this did not cause any problem. Other programs do have the very same effect.
What can I do to correct this problem?
