It is 2020, Safari TP 115
Copying video to WebGL texture is still very slow, way slower than in other browsers (Chrome and Firefox).

Checked with: 
Safari: QuickTime[HEVC with Alpha HD (1-1-1)] 540x960
Chrome/Firefox: Webm[VP09 with Alpha] 540x960.

Both texSubImage2D and texImage2D performance is unacceptable on Safari.
