Just faced strange problem when using combination of Python + pywebview. For big pages webview is blank while I can see that the page has all dom elements. This mean that page been loaded but not showing like webkit has some problems with a video driver.
If I use the standard example (pywebview.flowrl.com) everything is working, but bigger pages producing the blank screen. Also the blank screen may appear when resizing window.
Some info: there is enough memory , AppleWebKit/605.1.15, Python 3.6.9. It looks like everything is upto date.
Kindly asking for your ideas, it looks like I got stuck totally.
