Problem description

Linux FreeCAD releases use the same StartupWMClass across different versions. This causes desktop environments (like GNOME or KDE) to treat different versions (e.g., 1.1 and 1.2) as the same application, stacking them under a single icon.

Running two versions at the same time will stack all running instances under a single icon. This is often needed, if nothing else, to test working files against different versions.

Why is the StartupWMClass=FreeCAD same across all versions, and can that be changed to have unique name so that the running app can point to its own icon.

My proposal would be to assign unique name to major versions, 1.1, 1.2 etc.

For example on my installation I have designated icons for 1.1 and 1.2dev, and when running either of them the 1.2 icon would be underlined and stacked with a 2 badge .

Workbench affected?
