Sadly no. I’m just working with my external display. Do you also have version 460.73.01 and a 4K display? I really hope somebody on this forum comes to our aid soon.
There has been a new release, 460.80. However, it seems official channels on Ubuntu haven’t received that update yet. I really hope that it is available soon and that it fixes this issue. Else, this forum is my last hope.
I’ve actually asked the same question on superuser and answered it with a temporary workaround. No answers there so far.
