OpenCL image gives different result than buffer

[boxerab]

I have a test program here:

https://github.com/GrokImageCompression/latke

that performs the exact same image processing algorithm (debayer) using either image or buffer.

Using latest version of Neo driver, with buffer, I get a correct result (3 channel colour image). With opencl image, I get the wrong result (mono image: all three channels are equal).

Here is the ocl buffer result:

and here is the ocl image result:

This used to work correctly with older driver versions.

Please provide build / release driver version where it worked and where it is broken

[boxerab]

Thanks, how can I query the driver version?

[AdamCetnerowski]

Are you using the posted weekly releases? That number is good enough for us.

[boxerab]

Yes, I am using the weekly release. I don't remember the exact version when it was working.

By the way, I just tried the exact same code with my RX 480 card, and I get the correct result.

Unfortunately we can't find a working build, so this isn't a regression. This will go into our regular debug queue. We will update the issue if we have more information or a fix.

@AdamCetnerowski thanks - to clarify, you can't find a working build of the latke project ? I can help , with more details.

[AdamCetnerowski]

No, we got the workload to work. We can't find a driver version where the results would be correct.

ahhh I see. So, you can repro, great.
