Fresh install of xUbuntu 26.04 in two computers. Exact same settings, except one has Nvidia, the other intel GPU. In the Nvidia I can't see megasync and teams for linux when running. In the other, they do show up. This is confirmed in the Known Items menu of Status Notifiers. Maybe Nvidia bug? Can't think of another difference between PCs. UPDATE: now the icons disappeared from the Inter PC after a restart (and probably an apt upgrade).
