alpha/transparency displays incorrectly when using GPU acceleration
With GPU acceleration turned on in project settings, transparent graphics appear about 40 percent more transparent than they should. When GPU acceleration is turned off the graphics display correctly. This happens with both image files, .PSD, PNG etc., video files, CineForm, ProRes, and dynamically linked AE compositions.
I am using Premiere 14.0.3, RTX 2070 driver version 442.50, Windows 10.
Attached is a image with side-by-side screen grabs of a black graphic with various amounts of opacity over a light paper texture. Left side is the timeline with GPU acceleration off, right with the GPU acceleration on.

I figured out the problem, it happens when "composite in linear color" is checked in the Sequence Settings. Uncheck the box and transparencies display properly.
