Hello,
I'm trying to use Gem (from deb package) on a laptop with an AMD Ryzen 7 4800H with Radeon Graphics and a NVIDIA Corporation TU117M integrated on Debian 11 I installed nvidia drivers so as to use NVIDIA PRIME Render Offload as advised here https://wiki.debian.org/NVIDIA Optimus It seems to work, glxgear is much faster when using : __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia glxgears But when I try to create a big Gem window (1024x768) with or without NV PRIME, only a portion of this window can be used to show Gem objects or pix_film attached example is made with Gem example [translateXYZ 0 0 2.9] on a 1024x768 gem window
Sorry, I know it's not a Gem problem, glxinfo attached, any hint would be welcome as I don't really know where to dig
thanks Benjamin

no idea either.
but could you try using different windowing backends? also install the gem-plugin-[glfw3,glut,sdl] and use the following to interactively change the backend:
~~~ # update-alternatives --config gemdefaultwindow.pd ~~~

Hello,
many thanks IOhannes, while using the command :
# update-alternatives --config gemdefaultwindow.pd
it seems that my computer was on sdl backend by default :
- 0 /usr/lib/pd/extra/Gem/gemdefaultwindow-sdl.pd
70 mode automatique
I set it up to use glx as default backend and now it's working as expected with or without using nvidia card
