Bug ID: 482750
Summary: [wayland] Spectacle Rectangle Select / Multi-Display
screenshots blurry on unscaled displays when scaled
display in use
Classification: Applications
Product: Spectacle
Version: 24.02.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: General
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
SUMMARY
I have a display at 150% scale and several displays with no scaling. When
taking a screenshot, screenshots from the scaled display look crisp, but
screenshots on unscaled displays are blurry. This can even be observed when
activating the rectangle select, where unscaled displays become a little blurry
while the effect is active.
This issue does not occur when taking a single-window screenshot or
single-display screenshot, only with rectangle-select or a screenshot of all
displays.
I will attach a screenshot of the same text taken on the scaled display
(crisp), and then taken on the unscaled display (blurry). Then, finally, I will
attached a cropped single-window screenshot from the unscaled display (crisp,
like the scaled display).
STEPS TO REPRODUCE
1. Activate a Rectangle Select / Full-Display screenshot
2. Zoom in a little
3. Observe blur that does not occur with a screenshot of or on the same
display, taken as either a screenshot of the whole current display, or of the
active window on the same display that produces a blurry screenshot
4. Take a screenshot of any kind on the scaled display
5. Scaled display looks like screenshots do on previous Spectacle versions
prior to Plasma 6
OBSERVED RESULT
Screenshots on non-scaled displays are blurry only if Rectangle Select / Full
Display screenshots are taken. Single-display or single-window screenshots look
fine across all displays.
EXPECTED RESULT
Screenshots on non-scaled displays should look crisp across all displays.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Linux Zen 6.7.8 (Arch Linux)
KDE Plasma Version: 6.0.1
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2
ADDITIONAL INFORMATION
The filesize appears to be notably larger for screenshots on non-scaled
displays, even if the contents are identical. Maybe this is a result of the
blur.
