9 years ago Much of this sounds like the same polygon offset issue we have in the Android edition. It is a standard way to fix "stitching" and other artifacts when you render two coplanar surfaces with different textures/colors (e.g. shadow under mario, decals on walls). It seems that unlike the desktop platforms, the mobile hardware developers are inconsistent with their implementation of this. We had to add a hack to all the video plugins to permit us to change the polygon offsets depending on hardware. It's the only thing that differs between mupen64plus-ae's Rice video and the upstream version. https://github.com/mupen64plus-ae/mupen64plus-video-rice/commit/c7e10c487470bee0de32588366e4a375477529e4
It's a really inelegant and unmaintainable solution, but we haven't come up with anything better to date. Here is where we do it in glide: https://github.com/mupen64plus-ae/mupen64plus-ae/blob/45b0399132cb1c02a08b154d4a00fd767ca489ee/jni/mupen64plus-video-glide64mk2/src/Glitch64/geometry.cpp#L340

these issues might be in other games too, but i have only tested OoT and SM64 so far.
i am wondering if these are adreno only glitches?
floor textures flicker: in both OoT and SM64 textures which are directly above the ground flicker (it looks like parts of them go under the ground) this happens in OoT for example on the path from mido to the deku tree and in SM64 with shadows for example of trees or of mario himself.
shadows(?): in SM64 on the start screen (most obvious there) where you see marios head, his left eye appears normal colored and his right one appears too dark, also on double doors the left one appears normal and the right one appears too dark, happens on other characters faces too (left ok, but right too much shadow). In OoT links face seems to have too much/dark shadow.
moving ground: in SM64 right after loading a game and starting on the castles courtyard the ground appears to be moving (shaking as if there were an earthquake ;)), this happens in other places too. I don't remember if this happens in OoT too, but i think i saw it it once (can't reproduce it currently).
textboxes in SM64: In SM64 textboxes are broken (OoT textboxes work fine) only the last line of text is visible (the one where the arrow down is), if there is no last line nothing is visible. But one exception, wondrously dots are displayed correctly.
i would test if the glitches happen on desktop with GLES too but for some reason the GLES build on my desktop only displays a black screen (yes i have USE_GLES set for both core and video-glide64mk2)
none of these glitches appear in the OpenGL codepath on my desktop
