I just installed RStudio from RStudio's OBS repo. However it open very slowly and cannot display window menu when I starts it by clicking the shortcut nor by command line. The screen shot looks like this:
Also, I got following message when I starts it through command line:
Failed to register window menu, reason: org.freedesktop.DBus.Error.NoReply ("Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.")
More interestingly, RStudio can start seamlessly with window menu if I give focus to another program, like firefox or terminal, during RStudio's startup.
Does anybody encounter similar problem? How can I fix it?
According to this post and the bug report of the xfce plugin I used, this problem might relate to Qt. But the workaround does not work. It's weird since RStudio looks pretty fine in Xubuntu LTS 16.04 with the same xfce plugin few weeks age.
