Description Chiitoo 2020-09-13 15:02:48 UTC 
SUMMARY

After 4ebeb509 [1], any background (without set colour?) will be painted with the widget window colour, so for example something like a plain text file will be rendered with purple background instead of white (using the default theme of Falkon), if window colour was set to purple via, for example, the LXQt 'Window Color' setting in LXQt Appearance Configuration/Widget Style.

This also affects times when a new tab for example is opened: the window will flash with an unexpected colour.

STEPS TO REPRODUCE

1. Set widget window colour to '$someColour'.
2. Observe the normally white (default style) backgrounds be painted with '$someColour'.

OBSERVED RESULT

Backgrounds are painted with widget window colour.

EXPECTED RESULT

Backgrounds are not painted with widget window colour.

The change was reverted.

The idea behind it looks good and it can help in some cases, but it needs a bit more tweaking and toying before going to production.

Thank you for reporting.
