Bug with Resizing ImageBitmap causes slower than expected performance
There is currently a bug on Chrome Version 74.0.3729.131 (Official Build) (64-bit) (5/12/2019) with ImageBitmap where attempting to resize an ImageBitmap through ImageBitmapOptions will causes the resulting ImageBitmap to render very poorly when used with drawImage, even if the resulting ImageBitmap is resized to be smaller than the source image. |
