When I open RStudio in window view, it works perfectly fine, but if I enlarge the window to fill the screen, the menu bar and the open tabs disappear and stop working...
I use the latest win version, under win10. already tried to reinstall, reset the desktop (deleting folders from local and roaming folders), nothing helped.
Have you tried changing to software rendering?, you can change it by holding the Ctrl key while opening RStudio, then you should see this menu and change the "Rendering Engine" to "Software".
