When Rstudio main window is moved to the second monitor, the button "Show in new window" (from the Viewer or the Help files/Plots) opens the new window in an inexistent monitor and hence the new window is not visible. The new window does appear on the taskbar and if I right-click on its button and hit "Maximize" the window appears on the main monitor.
When the window finally appears on the main monitor, I can notice a blur effect like when dragging a window from one monitor to the other. In particular the effect is like the window was opened in a monitor to the right of my main monitor (which is an inexistent monitor).
If I keep the main Rstudio window on the main monitor, the problem disappears. This is, all new windows are opened and visible on the main monitor.
I did not have this problem in previous version of Rstudio.
I am working on a local computer (not remote desktop)
