06-8e-0b microcode has been updated to revision 0xde in microcode-20201110 release, does the newer microcode revision help?

[p1gp1g]

0xde doesn't correct this issue. (same CPU, i5-8265U)

New revision 0xea of 06-8e-0b microcode file has been published as part of microcode-20210608 release, it may be worth to try it out.
