Mario Kart Double Dash dark screen with OpenGL drivers

[retropiedude]

I'm getting the MKDD blue tint on lr-dolphin on a fresh manual install of RetroPie on my Raspberry Pi 5 (8GB).

However, there seems to be loads of threads from throughout the years and they all say the issue is the vulkan graphic backend and that I should switch to the opengl backend. However, based on the verbose log, I am already running the opengl backend.

Verbose log here

I'm using the official power supply, two USB devices (2.4g gamepad transmitters). RetroPie version 4.8.7. RetroArch 1.18.0 (Git 65dd99b)

I understand RPI5 is still a work in progress and lr-dolphin is experimental.

Replying to my own post. According to @mitu in this thread, this is due to an upstream issue in Dolphin.

I can't find the issue in the Dolphin bug tracker, although mitu indicated it's been logged there and will not likely be solved anytime soon.

However, mitu linked to this issue in the mesa driver which he indicated was the relevant bug.

There was already a bug report - https://bugs.dolphin-emu.org/issues/13416. Furthermore, the Libretro port is not maintained by the Dolphin team, so your report will probably be closed/forwarded to the libretro repository.
