This issue seems to have been fixed as of 5.8.3 kernel. I recently reported this upstream https://bugzilla.kernel.org/show_bug.cgi?id=208841 and after I was asked to re-test with the newer kernel, it turned out the problem no longer reproducible. I figured I should search if there were other reports of this problem, so here I am: if you upgrade to at least 5.8.3, the problem is absent.
