Ok, ok, But... how you can explain "random mysterious artefacts" when i have a WebGL ON... ???
Device Honor 8 with:
Chipset HiSilicon Kirin 950
CPU Octa-core (4x2.3 GHz Cortex-A72 & 4x1.8 GHz Cortex A53)
GPU Mali-T880 MP4
Similar on Samsung S8:
Chipset Exynos 8895 Octa - EMEA
Qualcomm MSM8998 Snapdragon 835 - USA & China
CPU Octa-core (4x2.3 GHz Mongoose M2 & 4x1.7 GHz Cortex-A53) - EMEA
Octa-core (4x2.35 GHz Kryo & 4x1.9 GHz Kryo) - USA & China
GPU Mali-G71 MP20 - EMEA
Adreno 540 - USA & China
On samsung i observed different artefacts....[but for end-user it is unacceptable ! ]
When i turned OFF WebGL...
ALL IS FINE!!! ZERO random mysterious artefacts.
Test Your APK on real devices not in DevKit on your PC this is my advice for all of us my dev. friends.
I will pray for a new WebGL library...
