From: Krunoslav Kovac <[email protected]> [Why] There's some unnecessary mem allocation for CS_TFM_ID. What's worse, it depends on LUT size and since it's 4K for CS_TFM_1D, it is 16x bigger than in regular case when it's actually needed. This leads to some crashes in stress conditions.
[How] Skip ramp combining designed for RGB256 and DXGI gamma with CS_TFM_1D.
