Steps to reproduce:
1. Open the attached user's project "OpenGLESURPRendereringIssue.zip"
2. Go to Project Settings > XR Plugin Management > Oculus and confirm that the Stereo Rendering Mode is set to Multiview.
3. Go to Project Settings > Player > Other Settings and check that OpenGLES 3 is the target API
4. Open the Build Profiles window and enable Development Build for Android
5. Build and run for Quest 2/3
Expected results: no errors are spammed
Actual results: GL_INVALID_OPERATION errors are spammed on Quest Development Builds when Multiview is selected with OpenGLES Graphics API
Reproducible: OculusXR 4.4.0 (6000.0.33f1)
Could not test on 2021.3.47f1 and 2022.3.55f1 due to "java.lang.RuntimeException: Unable to instantiate activity ComponentInfo" Exception
Could not test on 6000.1.0b1 due to an exception being spammed every frame preventing from building a APK "FormatException: Input string was not in a correct format. System.Number.ThrowOverflowOrFormatException" > Fixed, project provided in comments ([Internal link] )
Reproducible with these devices:
VLNQA00609 - Oculus Quest 3 (Quest 3), CPU: Snapdragon XR2 Gen 2 (SM8550), GPU: Adreno 740, OS: 12
VLNQA00415 - Oculus Quest 2 (Quest 2), CPU: Snapdragon XR2, GPU: Adreno 650, OS: 12
Testing Environment: Windows 11 23H2
Not reproducible on: no other environment tested
Notes:
-Issue only reproduces with OculusXR Plugin
-That error usually happens on VR when a shader doesn’t support Multiview. However, this is happening with the default shaders, which already have Multiview support
-Issue only reproduces on OpenGLES
-Issue only happens in Development Builds
-This error "Error Unity OPENGL NATIVE PLUG-IN ERROR: GL_INVALID_OPERATION: Operation illegal in current state" causes FPS drops, and it makes debugging and profiling more challenging
