Error
Works fine when using python webview_test.py. Opens a small empty webview window with the webpage displayed as expected. The following is how it is displayed when using the exe generated.
Looks like a window inside a window or something. Clicks and other interactions work on the location it should but the display is in wrong size.
The window is like this only when scrolled to extreme top, bottom or right side. If there is nothing to scroll, it remains weird. But when there is some scrollable area, as long as it is not scrolled to top, bottom or right end, it looks normal.
Does this involve some Qt bindings at all, or what is providing the Window?
This feels similar to a popular issue for Qt, namely that some plugins fail to work, due to dependencies not being included, which caused cosmetic errors. I will have to revisit the original case of yours, and see if my fix actually includes everything they say one should include.
