I upgraded to Chrome 85 (on MacOS High Sierra) last night. Today I'm noticing a number of strange display issues related to editing, I suspect they may be related.
When I'm editing a question or answer, I no longer see the live preview.
When I'm viewing a question, and someone edits the question or an answer, the edited item completely disappears until I refresh the page.
Is this just happening to me, or are others seeing similar problems? I'll check to see if disabling extensions clear it up, but I wanted to get this on the record first.
I use the Style Code After Edit Refresh extension, the author mentions that they changed something that impacts this. I'll try disabling until he announces the fix.
After disabling and re-enabling extensions a few times, the problem seems to have gone away.
It's still happening intermittently.
