OpenGL warning

[david berneda]

Maybe its a known issue, I'm trying to create a small reproduceable test project to attach here.

paserver shows a big quantity of these warnings:

"OpenGL Warning: Failed to get windows geometry for 000000000368c930, try xwininfo"

it happens when using the 2D TCanvas

It is really weird if you use 2D Canvas. It maybe internal Cairo back-end which is uses OpenGL, but we can't manage this
