Metal Issue on iPadOS with Xcode15

Hi, I'm using Whirlyglobe on iPad and iPhone and it worked fine so far until now. I upgraded to Xcode15, and now I have issues displaying the globe on my iPad. iPhone works without issues, but iPad throws the following error and doesn't display the globe anymore:

"Execution of the command buffer was aborted due to an error during execution. Ignored (for causing prior/excessive GPU errors) (00000004:kIOGPUCommandBufferCallbackErrorSubmissionsIgnored)"

When I deploy with Xcode14.3.1, everything works fine.

All systems MacOS and iPadOS, and iOS are updated to the latest versions, and I'm using MBP Max M1

any idea how to solve the issue? I guess it has to do with Metal... ?!

thanks in advance, M.
