FWIW today 3.38 was released to Arch stable repo and I tested it using
kernel 5.8.10 and 5.8.13. For the same governor, energy performance and
gpu min freq settings, stuttering in the overview has increased a bit
(HiDPI screen & 620, I think you already know that at this point).
Anyway I've seen many fluctuations since 3.34 when using different
kernels so it doesn't surprise me, seems like subtle timing issues that
probably won't be 100% fixed by freq scaling alone but also by the
additional buffering provided by !1441. Will take a look at Ubuntu beta
this weekend and let you know about my experience there.
