Popup menus and tooltips are not working when no displays connected

[andreymal]

Tested versions

4.2.stable

System information

Linux, X11

Issue description

I'm connecting to my PC remotely via VNC, and since the physical display is off, the system thinks there are no displays connected. Godot complains about it:

platform/linuxbsd/x11/display_server_x11.cpp:1062 - Invalid screen index: 0(count: 0).
platform/linuxbsd/x11/display_server_x11.cpp:1133 - Index p_screen = 0 is out of bounds (screen_count = 0).

Most functions work fine, however I have noticed that pop-up menus and tooltips don't work. I suspect that the menus are 0x0 pixels in size and therefore not visible.

However, the X11 screen still exists even without display, and I think Godot should work with it correctly.

Steps to reproduce

Unplug the display cable, I guess?

I still have this same issue when connecting to a remote machine using TeamViewer

You are using 4.3.beta1?

Ope, thought I was using the newest release, but I wasn't. Issue is fixed in 4.3
