I have managed to adapt glyphy to compile using ndk-build tool for Android platform and using cmake on Linux gcc environment.
It compiles and runs fine and I tested it on nVidia and intel integrated GPUs on Linux, but on Android I have problem running on some devices powered by
Adreno GPU - LG G3, Galaxy S4 and and Asus Nexus 7 2013. You can see the look of the text rendered on the following images:
Everything is rendered fine on Genymotion virtual machine and on the Galaxy S6 wih Mali T760 GPU.
I don't have any other devices to invesitage further, but I suspect that this has to be related wit the shader compiler for the specified GPU.
Is there anything I could to to avoid the problem?
