Notifications unreadable due to dark on dark text

[Mark - Syminet]

Upon upgrade to focal notifications are black text on very dark grey background, rendering them unreadable. I've attached a screenshot of how it looks after the upgrade.

Hovering over the notification in the popup makes the text turn the correct light color.

To make it readable, was able to change the CSS at line #1631 in this file:

/usr/share/themes/Arc-Dark/gnome-shell/gnome-shell.css

...to make the notifications background lighter, like so:

[...]

.notification-banner,
.notification-banner:hover,
.notification-banner:focus {
  font-size: 10pt;
  width: 34em;
  margin: 10px;
  padding: 6px 4px;
  color: #D3DAE3;
/* background-color: #383C4A; */
  background-color: #636883;

...not great but makes it readable at least.

This is highly likely fixed in 20.10 since this has a newer version of the theme.

Indeed it was - 20.10 does not have this issue. Hopefully we can get a backport to focal...

Anyway thanks a ton!
