GL Cores that not using "depth" are resulting in an black texture

[JustMeDaFaq]

Hi,
any cores (currently developing my own) where hw_render_callback->depth is false, the resulting texture done by framebufferrenderer.cpp is just black, game works tho sound is working etc. The framebuffer is valid and blitting it to the mainbuffer shows its correcty, so its probably related to the depth value.
(Same also happens to the Duckstation core, that one also needs retro_hw_context_type::RETRO_HW_CONTEXT_OPENGLES_VERSION tho)

Hi @JustMeDaFaq . I've been able to reproduce a similar issue with flycast (which actually uses the depth buffer). Does removing this line fix the issue:

LibretroDroid/libretrodroid/src/main/cpp/video.cpp

Line 182 in c56ded9

glDisable(GL_DEPTH_TEST);

@Swordfish90 Deleting that line didnt worked. For flycast (as also for PPSSPP) doing:
case RETRO_ENVIRONMENT_GET_PREFERRED_HW_RENDER: { LOGD("Called RETRO_ENVIRONMENT_GET_PREFERRED_HW_RENDER"); *((unsigned*) data) = retro_hw_context_type::RETRO_HW_CONTEXT_OPENGLES3 | retro_hw_context_type::RETRO_HW_CONTEXT_OPENGL; return true;

Should show the video (it expects the OPENGL one)

Hi @JustMeDaFaq. I've recently refactored the code and I found an issue with how the depth buffer was passed to cores. Is this issue still reproducible on the latest master?
