Starting Gazebo via MobaXterm, which has a built in X11 forwarding, as well as PuTTY with Xming starts with a black scene. The menu options to work. The --verbose flag doesn't reveal any errors nor warnings.

What it should look like: C:\fakepath\unnamed.png

What it does look like: C:\fakepath\blackscreen.JPG

Also testing via X2Go, we have to change the LD_LIBRARY_PATH=/usr/lib64/libgl-xlib:${LD_LIBRARY_PATH} following this suggestion and same issue but we do get these warnings:

[Wrn] [GuiIface.cc:122] X server does not support XInput 2
[Wrn] [GuiIface.cc:122] QXcbConnection: XCB error: 1 (BadRequest), sequence: 168, resource id: 78, major code: 130 (Unknown), minor code: 47

AL lib: (WW) alcCloseDevice: Releasing context 0x55b4ea4214b0
AL lib: (WW) alcSetError: Error generated on device (nil), code 0xa002

Any fix for this?
