When I started Maestro remotely using the commands:

ssh user -X
$SCHRODINGER/maestro -SGL

I got the error:

Xlib: extension "SHAPE" missing on display "localhost:10.0".
X Error: BadMatch (invalid parameter attributes) 8
Extension: 139 (RENDER)
Minor opcode: 4 (RenderCreatePicture)
Resource id: 0x420041f

What's the "SHAPE" that is missing?

The "SHAPE" extension seems to be related to graphics card driver settings in xorg.conf. It appears that you should be able to fix it by adding

Load "extmod"

to Section "Module" in xorg.conf:

The "SHAPE" module affects the look of the panels/windows (e.g., rounded corners) and its absence should not prevent you from using the software.
