Forums - Adreno-630 crash(IOCTL_KGSL_GPU_COMMAND, IOCTL_KGSL_DEVICE_WAITTIMESTAMP_CTXTID)

The Adreno-GSL log is here:

I meet the crash on  Samsung Galaxy S9 and Mi Mix 2S with Adreno-630 GPU inside. The crash happens when some specific meshs are used, But I couldn't find the difference betweet the crashed meshs and other meshs. The fragment shader is as follows:

precision mediump float;

uniform vec4 blend;

uniform sampler2D layer0;

varying vec2 otex0;

void main()

{

lowp vec4 fdiffuse = vec4(1, 1, 1, 1);

vec4 tex;

vec2 uv0 = otex0.xy;

tex = texture2D(layer0, uv0);

fdiffuse.xyz *= tex.xyz;

fdiffuse *= blend;

gl_FragData[0] = fdiffuse;

}

precision mediump float;

uniform vec4 blend;

uniform sampler2D layer0;

varying vec2 otex0;

void main()

{

highp vec4 fdiffuse = vec4(1, 1, 1, 1);

vec4 tex;

vec2 uv0 = otex0.xy;

tex = texture2D(layer0, uv0);

fdiffuse.xyz *= tex.xyz;

fdiffuse *= blend;

gl_FragData[0] = fdiffuse;

}

And if I remove the "uniform vec4 blend",  keep lowp for "fdiffuse",  the app will not crash.

precision mediump float;

uniform sampler2D layer0;

varying vec2 otex0;

void main()

{

lowp vec4 fdiffuse = vec4(1, 1, 1, 1);

vec4 tex;

vec2 uv0 = otex0.xy;

tex = texture2D(layer0, uv0);

fdiffuse.xyz *= tex.xyz;

gl_FragData[0] = fdiffuse;

}
