Doom 64 Graphic Issue

[MoeFoh]

Platform / OS / Hardware: Windows & Android

Flycast version: 2.4

Hardware: Android Tablet, Windows 11 Laptop

Is this fixable? The weapon just shows a box, but still works. Tried full frame buffer and all the different graphic api's - no change.

It may be using SQ's to output directly to VRAM, I'm not sure.

Use per pixel:

I only get - "per stripe" and "per triangle" options on this older tablet. Will try a newer Android tablet later. And also test "per pixel" with Windows setup.

On mobile you need to select Vulkan to have the per pixel option.

OK, working now. Occasional "snow" in upper-left hand corner with Vulkan. Does not happen with OpenGL. Probably not a Flycast issue. I'm using a Lenovo tablet with Android 13 with all the updates. Flycast is v2.4-27.

Common issue with Mali GPUs when using per pixel.
