It seems that (at least HD4400) Intel GPU fails tasks at the moment https://minecraftathome.com/minecrafthome/result.php?resultid=2485243 |

Yes, it seems your Intel 4000 GPU only has OpenCL 1.2 and not 2.0. AMD and Intel keep to the standards, and so if we request a compatible GPU, it's likely that OpenCL 1.2 GPU cannot run the tasks. Nvidia GPUs with OpenCL 1.2 work surprisingly, at least from the 700 Series (Maxwell) and onwards. We have not set device compatibility limits/checks yet in our configs, but I know the latest binaries work for me on my Linux Intel OpenCL : UHD 620 graphics. (Opencl 2.0 drivers) INTEL Intel(R) HD Graphics 4400 (1629MB) OpenCL: 1.2 Of course, make sure you have the latest Intel drivers for your GPU and any OpenCL drivers that Intel may have put out for your (older) generation as well. I can look into this later but I need to ask if you have any other graphics cards (Nvidia, AMD) in your computer as well |

True - it is only capable of OpenCL 1.2. Installed (forced) the latest and greatest driver from Intel: 02/07/2020 18:05:31 OpenCL: Intel GPU 0: Intel(R) HD Graphics 4400 (driver version 20.19.15.5126, device version OpenCL 1.2, 1630MB, 1630MB available, 160 GFLOPS peak) 02/07/2020 18:05:31 OpenCL CPU: Intel(R) Core(TM) i3-4030U CPU @ 1.90GHz (OpenCL driver vendor: Intel(R) Corporation, driver version 5.2.0.10094, device version OpenCL 1.2 (Build 10094)) Still spitting errors out though. There is no other GPU in the system. |

We have pushed out a change to set the minimum required version of OpenCL to 200 for Intel graphics. This will remain in place until we have tasks which may be compatible with older versions. |

We have pushed out a change to set the minimum required version of OpenCL to 200 for Intel graphics.That means according to https://www.intel.com/content/www/us/en/support/articles/000005524/graphics.html: Intel Iris Plus Graphics (OpenCL 2.1)These are only available on generation 5 (Broadwell), generation 6 (Skylake) and above Intel CPUs. |
