Hell yes, I just spent half a day theming my Linux box with Chicago95! I've already got Space Cadet pinball from Flatpak, and now I've got Solitaire - nostalgia levels are off the charts right now B-)
When I used the workaround, the taskbar lost its 3D border effect, so I recovered that by using a background image that is 1 pixel wide and has the correct colors to have the 3D effect. It’s better if you use something like Xubuntu 22.04 first to see how it should look like without this bug.
