After upgrading to Big Sur, it seems Opera is consuming more resources. I often hear the internal fan starts spinning and Activity Monitor points that Opera's GPU process is consuming the most energy. Is there a way to find out which tab is using the GPU most?

@tkurosaka The task manager would be the best bet. On Windows, it's Shift + Esc.
