Description

What's the problem? Describe what went wrong.

All forms of stereoscopic 3D on the Android version of Dolphin don't function properly on at least 3 different phones (Pixel 2 XL / Xperia XZ1 Compact, both with Snapdragon 835 and Adreno 540, and pixel 3a XL, with Snapdragon 670 and Adreno 615, the latter two running Android 9)

Side By Side only shows the left image, Top and Bottom only shows the top, and Anaglyph is nearly indistinguishable from normal gameplay, save for some slight rendering differences.

What steps will reproduce the problem?

Graphics Settings > Enhancements > Stereoscopy
Enable any stereoscopy mode
Run any game

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes, the latest version is 5.0-12103

Is the issue present in the latest stable version?

Yes, 5.0-11991

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

Attached are 3 screenshots. Sidebyside.png demonstrates the left-image issue, anaglyphon.png demonstrates what Anaglyph looks like when enabled, and anaglyphoff demonstrates what the game normally looks like.

What are your PC specifications? (CPU, GPU, Operating System, more)

Snapdragon 670, Adreno 615, Android 9, Pixel 3a XL

What kind of settings do you all have enabled?

Is MSAA enabled? If so, can you try turning it off?

The other unfortunate possibility is that some devices that don't support geometry-shaders (like the original Quest, not sure about Quest2) and will render black in one eye, so it's possible that's the issue..

Edit: previous screenshots and descriptions weren't quite informative enough. Dolphin's internal screenshot doesn't show the problem.
