@scifijunkie A cursory inspection in the Profiler of Vivaldi (Chrome-based) doesn't show any particular spike in memory consumption when I open my Global community page, if I read the graphs correctly. The tab itself takes about 100MB of memory (as much as other Friendica tabs), but I don't know how much of the 1.1 GB of GPU memory is used for this specific tab as the task manager doesn't have this kind of breakdown.
