backward tracking working ok with 1.10 here but seems to have an occasional jitter which I don't think I had before
Intel 5820K OC@4Ghz, Titan X (Maxwell), 32GB Corsair Vengeance DDR4, ASRock X99 Taichi, Samsung 500Gb 960 Evo M.2, Corsair H100i v2 Cooler, Inateck KTU3FR-4P USB 3 card, Windows 10 Pro v20H2 (19043.1081)
We found the problem and created a patch. It does take some time to reach everyone, but many people should have got the fix already and more will shortly. Thanks.
