Jetson Nano problem with pywebview, blank screen

[xaribda]

Hi.

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.

Hi,
We don’t have much experience in the use-case. Would see if other users can share experience.

Not sure but this probably helps:

Found solution, all you need is turn off the hardware acceleration. Webkit will probably work slower but stable. This can be done by setting up an environmental variable WEBKIT_DISABLE_COMPOSITING_MODE.

export WEBKIT_DISABLE_COMPOSITING_MODE="1"
