Negative. I checked back as far as the DC/DAL was integrated (4.15) and it's
been there from the start.=20

It's in the kernel somewhere, in the DC DRM layer above the device specific

suspect Michel's suggestion for async cursor updates might be the fix, but I
can't help wondering why the legacy DRM code is unaffected.
