nw.js: Extremely slow after updating from v0.50.1 to v0.52.1 and later

NWJS Version : 0.52.1 and 0.53.0 Operating System : MacOS and probably others

Expected behavior

Same rendering speed as v0.50.1 and earlier.

Actual behavior

GUI rendering is at least a factor 10 slower than in v0.50.1.

How to reproduce

git clone https://github.com/pragma-git/pragma-git.git cd pragma-git git switch develop /Applications/nwjs.app/Contents/MacOS/nwjs . # On mac, use similar on other platforms You may also click the “question-mark icon” at the top left corner, or the “settings icon” at the lower right corner, to observe more of the slow rendering

I have also tried the following

--disable-features=nw2 flag in above run command removed "chromium-args": "--disable-gpu" in package.json
