It seems to consist of 7 i915 updates c09d39166d8a3f3788680b32dbb0a40a70de32e2 DRIVER_DATE to 20190207 47ed55a9bb9e284d46d6f2489e32a53b59152809 DRIVER_DATE to 20190220 f4ecb8ae70de86710e85138ce49af5c689951953 DRIVER_DATE to 20190311 1284ec985572232ace4817476baeb2d82b60be7a DRIVER_DATE to 20190320 a01b2c6f47d86c7d1a9fa822b3b91ec233b61784 DRIVER_DATE to 20190328 28d618e9ab86f26a31af0b235ced55beb3e343c8 DRIVER_DATE to 20190404 ad2c467aa92e283e9e8009bb9eb29a5c6a2d1217 DRIVER_DATE to 20190417 So I figured I'd see if I can locate the problem by bisection of those plus inspection.
