I'm experiencing a slowdown on typing and scrolling speeds on notes that have a lot of images in them. I tried a few things:
First I thought that maybe the images were too big but the lag is barely better with dramatically smaller images.
Next I thought maybe there's too many images but I get the same problem with 4 images that I do with 20.
I'm using png images around 400k each and that note is completely unusable for me, even at my slow typing speed.
I'm using 7.14 on Catalina 10.15.2
