Summary0000175: Symbols not rendered properly with dark theme selected
DescriptionWhen a dark Qt theme is selected, symbols are rendered partly in black and partly in white. As a consecuence, part of the symbols disappears on white background and the diagram seems to be "incomplete".
Steps To ReproduceFor quickly switching theme I use the following commands:
$ QT_QPA_PLATFORMTHEME=gtk2 qelectrotech # Dark because I've a dark GTK+ theme enabled
$ QT_QPA_PLATFORMTHEME=fusion qelectrotech # Bright
Additional InformationIn the attached image, on the left you can see a page opened with a bright theme (fusion) while on the right the same page is opened with a dark theme (gtk2, with a dark GTK+ theme selected). I tried some different theme combinations by using `qt5ct` and the problem seems to affect all dark themes.

As a workaround, you can put the following CSS fragment into `$HOME/.qet/style.css` to force drawing everything in black:

QGraphicsView {
  color: #000;
