Problem with ComputeShader and RHalf RenderTexture

There is a simply compute shader:

 #pragma kernel CSMain
 
 RWTexture2D<float> _Texture;
 
 [numthreads(32, 32, 1)]
 void CSMain (uint2 id : SV_DispatchThreadID)
 {
     _Texture[id] += 0.1;
 }

Code which creates a RHalf RW texture:

 texture = new RenderTexture( 32, 32, 0, RenderTextureFormat.RHalf, RenderTextureReadWrite.Linear );
 texture.enableRandomWrite = true;
 texture.filterMode = FilterMode.Point;
 texture.Create();

And shader using:

 shader.SetTexture( 0, "_Texture", texture );
 shader.Dispatch( 0, texture.width/32, texture.height/32, 1 );

But I'm getting a strange behavior.

Why is it?

RFloat works good.

Also just setting constant value works good.

But reading and writing RHalf doesn't work.
