Comparison between Chromium and Firefox on KDE
SUMMARY
After a recent update, all windows of Chromium (and Chromium-based browsers,
like Brave) are tinted light. See attachment "Comparison between Chromium and
Firefox on KDE".
In KDE, a solid black DIV in Chromium is rendered as (according to
KColorChooser) #101010 instead of #000000.
As you can also see in that attachment, because I have Wobbly Windows enabled,
when I start dragging the window, the color turns normal; but when I drop the
window, it becomes tinted light again. Entering the workspace grid/overview
also turns the colors normal, until I exit the grid/overview. If I disable
Wobbly Windows, then dragging the window no longer makes the colors temporarily
normal.
This is not happening in GNOME, so I know it's specific to KDE and is not
solely caused by my underlying hardware and/or Chromium itself. This happens
whether "Color accuracy" is set to "Prefer efficiency" or "Prefer color
accuracy." I've also tried forcing Chromium to use the sRGB color profile in
its own internal settings, which had no effect (I've since reset the flag that
I overrode while troubleshooting that way).
I did click try changing my "Color profile" setting from "None" to the other
two options semi-recently (for no reason other than experimentation while
researching displays), so that setting could be involved here. However, I had
changed the setting back to the default "None" before this started happening,
and I've since reset many of my KDE settings trying to troubleshoot this,
including removing the config file for my display configuration.
STEPS TO REPRODUCE
1. Install a Chromium-based web browser
2. Navigate to a webpage with black or dark colors visible
OBSERVED RESULT
The colors are tinted slightly lighter than they should be.
EXPECTED RESULT
Black should be rendered as black.
