From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

From the article...
On Wayland, KWin can now be configured to pull color profile information from the monitor’s EDID metadata where present. Note that color profile information in EDID metadata is often wrong, so use this setting with caution.
Can anyone speak towards why the EDID metadata is often wrong?
Edit: TY to all who responded.
Most displays provide settings to modify the colors of your screen; mine has like 10 different "picture modes" that strongly modify gamma curves, colors and the whitepoint. The EDID only describes colors of one of them, so if you change display settings, the data no longer applies.
More generally, the information isn't used by Windows or other popular video sources by default, so manufacturers don't have much of an incentive to put correct information in there. If it doesn't make a difference for the user, why would they care? Some displays even go so far as to intentionally report wrong physical size information, to make Windows select the default scale the manufacturer wants to have on that display (or at least that's what I think is the case with my cheap AliExpress portable monitor)...
That's not to say that the information is actually often completely wrong or unusable, but if one in tenthousand displays gets really messed up colors because we toggle this setting on by default, it's not worth it. We might add some heuristics for detecting at least usable color information and change this decision at some point though
A few reasons:
I wouldn't call it often wrong, personally. I'd say some devices are really bad with EDIDs, and are consistently problematic. It's more like -recent hardware is generally pretty good, but relying entirely on EDID won't always work, so use with care.
Some great examples of problematic devices/situations (in general):
If you've got a single PC going to a display (or several), just set it once manually and you're good to go. If you're plugging and unplugging often with multiple devices (like with a dock), an EDID minder can be handy, but come with a price that generally makes setting it manually preferred anyway.
Hope this helps answer for you
Hell yeah!! So many needed fixes that have been bugging me for a while are finally fixed!!
also making things more minimalist where needed
Really happy to see them continuing to improve on their multi-monitor support.
And the regression from last patch with drag and drop freezing Dolphin entirely seems unfixed. Honestly I think it's the first time in 7 years I'm affected by an annoying KDE bug, but it still stings regressions are not first priority :(
They're probably waiting for the person that did the patch to fix it, and life gets in the way sometimes.
I've just checked and it's fixed. Must have sliped by me.
youve reported it already?
I found a report so I didn't do it myself again. It seems it's fixed even though the report isn't.
Small in-window dialogs in QtQuick-based software have gotten a visual overhaul to remove everything not visually necessary, which gives the text and buttons more focus (Carl Schwan, Frameworks 6.3. Link 1 and link 2)
Eww noo
