I'm running RStudio 1.2.5001 in a VM running Ubuntu 18.04.1. (10 GiB of RAM)
RStudio is barely usable because whenever Copy-Paste into RStudio is performed it hangs for 30+ seconds after which a copy may or may not have succeeded. This happens for both guest-guest copy-paste (i.e. copy-paste inside the VM) or host-guest copy-paste (i.e. copy-paste between the host machine and the VM).
The first 4-5 pastes after restart may actually succeed, but after that it's curtains.
It may also arbitrarily hang for a few seconds when typing in the Console.
There is no particular I/O or CPU activity and other processes in the VM do not exhibit that behaviour.
I have noticed that restarting the "spice-vdagentd" daemon process when RStudio hangs immediately brings it back to life (the paste is lost though), so there may be a problem interworking with the clipboard.
Is there something I can try to keep working without ripping my hair out...
