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.
