Daniel, A few items to make sure I'm on the same page:
1. So, IIUC, you're saying that the "final fix" should be the vv5 package, which contains the fix to the zero hz bug (loosening mutter to accept zero-Hz, as this is the bogus refresh rate being reported by Xdcv) + the caveat for AWS to either fix Xdcv or never try to enable Fractional scaling in the instance (details in your comment#16), is that so? 2. Regarding your comment on bug 1857392 and bug 2007742 being present, iiuc they do not have a noticeable impact (other than spamming the log). 3. Also, I need to mention that I went ahead and tried once more the vv5 package on a AWS Workspace, and I can no longer reproduce the blank screen. Now I see these logs [1] and the scale does get reverted from 200% to 100%. https://pastebin.ubuntu.com/p/JpVsjbQzsQ/ 4. If 1 above is correct, then where (if anywhere) we are going to investigate the situation where vv5 causes the other monitors to get automatically enabled?
