Control: forwarded -1 https://lore.kernel.org/lkml/d05aba2742ae42783788c954e2a380e7fcb10830.ca...@scientia.net/
Hey. I've forwarded this to lkml. My most recent post in that thread[0] contains an pretty elaborate test series comparing kernel 5.2 vs. 5.4 (each with intel_pstate=disable and without), each on Cinnamon and GNOME Classic... under different scenarios (idle system and several videos played back). My personal conclusion would be that something changed between 5.2 and 5.3, which made temperatures and CPU utilisation considerably worse for Cinnamon,... and not such much, but still noticeably for GNOME. Apart from that however, there seems to be additionally something wrong with Cinnamon, as it performs much worse with video playback than GNOME does - even under 5.2. So I've additionally created a ticket there at Cinnamon[1].
