Thanks for the post, this is extremely interesting to me for metal, what version of macOS are you using in what computer that can’t find the slice?
I think, the error message "Unable to find intelgpu_kbl_gt2r0 slice or a compatible one" strongly suggests that it is related to the performance of the app on your Mac running macOS 26.2. This is a specific "slice" or compilation target for Metal shaders.
This file contains precompiled Metal shader code for various graphics hardware configurations. The error means the system couldn't find a version of a shader that's compatible with your specific Intel graphics processor in the precompiled resources? The error message you're seeing is a strong indicator of a graphics-related issue likely impacting performance on your Intel Mac. The specific version of macOS and the applications you are using will determine the scope of the impact and the appropriate troubleshooting steps.
I’m not an expert in metal nor I know enough to figure it out. May I ask you to submit a bug for this slice so I can forward to the correct team? Also please provide information about the machine you are encountering the error and the chip itself. Is it an Intel macOS? Have you tested this in any other machine? macOS version and Xcode version too please.
Once you open the bug report, please post the FB number here for my reference.
