Unity5 Android GPU Crash

Questions & Answers

Hi I’m working on a kind of 3D brick breakoutgame for mobile devices.

After my 3rd day of work it’s now happening really often that my testdevice “Huawei P8” is crashing after playing a while. Sometimes also after a few seconds of playing.

For me it seems to be a crash of the GPU. It looks similar to this picture:

If this happens I can’t do anything except of waiting. After a few seconds the screen is refreshing and it is possible to continue play.

Now I’m not shure, is this a problem of the Unity version, in my case Unity 5.3.5p6, an optimization problem or simply has my mobile a problem?

This is a screenshot of my game if this might help to analyze the problem:

The most shaders are the standard Unity mobile shader, except the plants. For this I uses the nature leaves shader.

The most objects are static and I use baked light maps.

Thanks in advance

Seems that the problem was the Mali GPU and texture compression problems. I optimized my plant textures and shaders now for Mali GPU and better mobile performance and now it seems to run fine.

But I will keep an eye on it.

Thanks Ill fish - I will double check my settings and let you know how I get on - I have tested with a bunch of shaders - mobile, legacy, latest etc - with little/no difference. There are definitely issues in Unity surrounding the Mali GPU - the sample project I produced was confirmed to cause a crash by Unity themselves, but not on their BETA. My full project still crashes on BETA however. Will let you know how I get on and if I discover anything else.
