Vulkan issue: Godot shall be in "compatibility" mode instead of "forward+" mode #57

loading the cef shared library into Godot seems to cause it to be unable to use Vulkan so the main forward+ renderer can't be used... I wonder if instead of passing a window handle which needs a GL context we can use the offscreen renderer with GPU disabled and copy the texture to an image that can be loaded in the Vulkan renderer?

ERROR: Required extension VK_KHR_xlib_surface not found, is a driver installed?

Workaround is not to used CEF's libvulkan.so

in gdcef/addons/gdcef/gdcef/src/gdcef.cpp remove "libvulkan.so.1",
recompile the project
remove the libvulkan.so.1 which is copied in build folder
start godot and the project
switch to "forward+"

Same idea for libEGL.so libGLESv2.so ?
