I use remote desktop web client for my school's virtual lab computers. Ever since I updated macOS monterey to 12.3 and started using Safari v15.4 I've had flickering/black/blank/gray display issues and only little squares of screen content show intermittently when I attempt to resize the window, although nothing has worked. I am using chrome in the meantime to work around this issue, but please provide a fix soon!
(i also have "enable native display resolution" option turned off just FYI)
have also tried turning off all extensions, resetting all browsing data, and browing in private window /:
