Space and Settings

• The active tabs (checkboxes) in the navigation (toolbar) differ from the inactive tabs
  the non-active tabs only by the background color. The
  contrast requirements are not met, as the contrast ratio between active and inactive
  active and non-active tabs is less than 3:1, at only 1.1:1.
  increasing the contrast, emphasizing the labeling with bold print or adding a frame color.
  by using bold print or adding a frame.

Server activity and Synchronization protocol

• Active tabs such as "Server activity" differ from the inactive tabs

  contrast requirements are not met, as the contrast ratio between active
  active and non-active tabs is less than 3:1, at only 1.4:1.

About tab contrast:

For me (on mac) the contrast is fine. Which platform is this tested on?

[erikjv]

For Windows most contrast issues are fixed by using the "High Contrast" theme.

@erikjv Could you gather a bunch of screenshots with the high contrast theme?

[erikjv]

With the "Aquatic" contrast theme on windows 11:

With the "Glow" (non-contrast) theme (Win11):

For both: I've set my laptop to use a smaller default font.

Could you also test with a build where:

client/src/libsync/platform_win.cpp

Lines 69 to 70 in 3338411

	QApplication::setStyle(QStringLiteral("fusion"));
	QQuickStyle::setStyle(QStringLiteral("Fusion"));

is commented out?
As those two look pretty similar....

[erikjv]

What is still a problem are the tabs in the activity view: the fusion theme (and the new Windows theme) do not show much contrast between active and inactive tabs
