NGUI 3 Support / Android Adreno issue
« on: July 15, 2014, 07:16:00 AM »
Hi all,
We're currently having issues with Adreno GPUs and our NGUI setup. We're working with Unity 4.5.1f and NGUI 3.5.8, currently we're forcing GLES 2.0 through the project settings.
We have a splash screen, right at the start of the game, which is displayed within a UIPanel. On first run the game will boot up and often go black when the splash screen should be displayed. After this nothing will render. Adding a delay before the splash seems to alter this timing a little. On failed runs it will output the following:
W/Adreno-EGL(22425): <qeglDrvAPI_eglGetConfigAttrib:542>: EGL_BAD_ATTRIBUTE
W/Adreno-EGL(22425): <qeglDrvAPI_eglGetConfigAttrib:542>: EGL_BAD_ATTRIBUTE
Followed by the GPU spamming out:
W/Adreno-EGLSUB(20362): <SwapBuffers:1382>: Invalid native buffer. Failed to queueBuffer
W/Adreno-EGLSUB(20362): <updater_thread:456>: native buffer is NULL
Subsequent runs seem to stand a better chance of getting through, although on the Nexus 7 (2013) we've had it repeatedly fail. Given it's working on future runs I'm assuming it's likely to be related to shader compilation?
I fixed the issue by switching to GLES 3.0, but then we get issues compiling NGUI shaders. Specifically "unlit/premultiplied colored 1" gives me the errors:
E/Unity(14343): -------- GLSL error: Vertex shader compilation failed.
E/Unity(14343): ERROR: 0:6: '' : GLSL error: #version must occur before any other statement in the program
E/Unity(14343): ERROR: 0:37: 'uniform' : cannot initialize this type of qualifier
E/Unity(14343): ERROR: 0:38: 'uniform' : cannot initialize this type of qualifier
E/Unity(14343): ERROR: 3 compilation errors. No code generated.
Has anyone had similar? The game is running fine on iOS so I'd really like to avoid any big changes to get things sorted.
Thanks!
