52.6.0 (64-bit) on Ubuntu 18.04. On both gnome on Xorg and gnome on Wayland the progress bar uses 100% of one of my CPUs. I know that if there is no other task a modern CPU tends to be in sleep mode most of the time (which makes the only task automatically reach 100%). But the progress bar also drains my battery in ca. 40 minutes and makes the CPU fan go haywire => it seems to be hideously inefficient.

This seems not to be necessary. If the sending failed and an corresponding error message dialog appears, the CPU is still being used. When pressing ok to close the error dialog the CPU is fine. This suggests it might be related specifically to the progress bar. Such behavior is especially annoying on a laptop where you can hear the CPU usage because of a starting fan.
