Bug ID: 495492
Summary: Screen capture with ability to bypass zoom + color
inversion
Classification: Plasma
Product: kwin
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: alkalinethun...@gmail.com
Target Milestone: ---
SUMMARY
As an accessibility user, sometimes I want to take screenshots or record video
of my screen while zoomed in/with colors inverted, but don't want the viewer to
see this. Currently, as this is a fairly unique requirement, it isn't possible
to do this in any compositor, including Kwin.
STEPS TO REPRODUCE
1. Zoom into the screen, or invert colors.
2. Take a screenshot with Spectacle
OBSERVED RESULT
If you had color inversion turned on, that will appear in the screenshot. If
you were zoomed in, the screenshot will be as well.
EXPECTED RESULT
The above observed result is fine in a lot of cases, but sometimes you don't
want this. Operating systems like Windows and macOS allow you to bypass zoom
and color inversion when capturing the screen. This way, as an accessibility
user, you don't need to worry about turning accessibility features off when
sharing your screen with others who don't need them/find them bothersome to
look at.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux
KDE Plasma Version: 6.2.2
KDE Frameworks Version: 6.7.0
Qt Version: 6.8.0
ADDITIONAL INFORMATION
This isn't really a bug, more or less just a missing feature. It's also fairly
unique to visually impaired people like myself, which is why I marked it as
wishlist. I suspect this would need a wider dialogue outside of just the KDE
community, as I'd imagine this would require extending some Wayland protocols.
That's beyond my skill level though, I figured I'd start the dialogue here
where people know what they're doing.
The real question is why you'd want a feature like this. Over the years of
making YouTube videos and doing livestreams where my desktop is part of it,
I've received lots of feedback (and even jokes) about how far I have to zoom
into the screen and how much things move around. While most people are polite
about it once I let them know I'm blind and there's nothing I can do about it,
the biggest complaint is that people find it nauseating to watch. I don't blame
them - it does take a while to get used to using a computer zoomed in, finding
the most comfortable zoom level and mouse movement mode, etc. Being able to
bypass that in a screen capture would make everybody's life easier - I can stay
zoomed in so I can see what I'm doing, but everyone else can watch without
developing motion sickness from the constant movement of UI elements.
Based on my (limited) understanding of the zoom effect in kwin from a previous
contribution, I'd imagine this would require direct support from the
compositor.
