Stencil buffer and depth buffer
Posted: Tue Oct 15, 2019 11:20 am
Hello! I built Qt libraries to work on drm/fkms. I tried to run applications that runs properly on any pi on the old gles2 driver on dispmanx, and I'm getting this:
Is this correct or maybe there is something wrong in my env/Qt build? Is there really no support on fkms for depth and stencil buffers?
Thanks.
EDIT: This is more precisely what Qt reports:
Code: Select all
Warning: Setting a new default format with a different version or profile after the global shared context is created may cause issues with context sharing.
