Probably best would be to report upstream as it happens on the recent stable version. Maybe they will ask to test on 4.19-rc1, but it should work on the latest stable version nevertheless.
reported bug to upstream: https://bugzilla.kernel.org/show_bug.cgi?id=200987
According to upstream bug, problem was fixed in 4.19-rc2.
