See

In short: install package qgis-dev (nightly build) and download DebugView.

Works with me here, no crash (Debian Buster):

Type: GPU
Name: Intel(R) HD Graphics Kabylake Desktop GT1.5
Vendor: Intel
Profile: FULL_PROFILE
Version: OpenCL 2.0 beignet 1.3
Image support: True
Max image2d width: 8192
Max image2d height: 8192
Max mem alloc size: 3221225472

You could

About crashes... anybody can confirm this one (non opencl but 3D/OWS
