Hi there! To save me some time, can you share more about what debugging steps you've already tried?

Hi! A few things worth noting: 1. The code stopped working after a driver update, 2. Some OpenCL programs also stopped working properly but not all of them. So it's definitely an issue with the drivers, so the first thing I tried is changing the packages that provide OpenCL to beignet, intel-opencl, pocl and intel-opencl-runtime with no success, reinstalling the nvidia drivers also yielded no results, I also tried to look for any memory errors with oclgrind but nothing interesting came up.

Also, clinfo correctly detects my device

After several driver updates it works fine, closing the issue.
