[BUG] Transparency not handeled correctly

[akrea]

Describe the bug System setup:

• Wallpanel used to display Grafana Dashboard.

• Grafana dashboard (black background by default) contains an iframe for weather forecast.

• Weather forecast widget is provided by https://www.meteoblue.com/de/wetter/widget/setupthree/obergrossegg_schweiz_11579273

Bug: Since the last update of wallpaper the transparency-setting ist not handeled properly. The background remains white. Although everything else on the site is dark.

To Reproduce Use an iframe in Grafana and set it to transparency.

Theory to occurring bug I think a dark mode of the wallpanel itself (not just settings UI) would solve the problem. The recent upgrade to Grafana 8 may brought changes to CSS-handling which may have an influence on this issue.

Smartphone (please complete the following information):

• Device: Samsung Galaxy Tab A7
• OS: Android 11
• Applicaiton version 0.9.5 build 6

But WallPanel does nothing with the webpage CSS or code. WallPanel has it's own dark mode, not sure if this is changing the default background of WebView component, but I think its' up to your webpage to handle background color.
