PTGui Pro 13 (Linux) - Error: OpenCL error: CL_BUILD_PROGRAM_FAILURE (-11) in function clBuildProgram

[Matthew Miller]

I just upgraded from PTGui Pro 12.27 (which worked flawlessly) to PTGui Pro 13.2, now I am getting the error "error: CL_BUILD_PROGRAM_FAILURE (-11) in function clBuildProgram" and it no longer uses my OpenCL compatible Intel Iris Xe nor Intel Iris Xe Max GPU for stitching (leading to REALLY slow performance).

PTGui Options dialogue says "The installed driver is outdated.  Please download and install the latest driver from intel.com" but the Intel website says Linux Kernal 5.7 or newer has the drivers in it for my main Xe GPU and kernel 5.16 or newer has the drivers for my Xe Max GPU.

Help?

OS is Linux Mint 22.1 (Ubuntu 24.04-LTS based)

Hardware is a Dell Inspiron 15-7506 Black Edition

GPUs:

Intel Corporation TigerLake-LP GT2 [Iris Xe Graphics] [8086:9a49] (rev 01)
Intel Corporation DG1 [Iris Xe MAX Graphics] [8086:4905] (rev 01)
