Summary: Spectacle screenshots of maximised windows include
extra padding when the "Include window shadow" option
is enabled
Classification: Applications
Product: Spectacle
Version: 24.08.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: General

Target Milestone: ---
SUMMARY
Since Spectacle 24.08, when taking a screenshot of maximised windows, Spectacle
still tries to include the window shadow. As there is no shadow for maximised
windows, this creates a border around maximised window screenshots where a
shadow would be were the window not maximised, resulting in a larger filesize;
with my shadow configuration, windows maximised on a 3840x2160 display now have
screenshots with a width of 3900, adding roughly 30 pixels extra on each side.
Disabling the "Include window shadow" option fixes this issue.
This negatively impacts taking screenshots of, for example, game windows, in
particular when Spectacle is used to silently take screenshots without the UI.
This happens with any action that can take a screenshot of a single window,
which to my understanding are the "Active Window" and "Window Under Cursor"
options.
This was not present in the previous version of Spectacle I used before
updating to the new version today with KDE Gear 24.08. I believe the previous
version was 24.05.2.
STEPS TO REPRODUCE
1. Maximise a window
2. In Spectacle, ensure the "Include window shadow" option is enabled.
3. Take a screenshot of just this window, using either "Active Window" or
"Window Under Cursor"
4. The resulting screenshot has extra padding where the window shadow would be.
5. Disable the "Include window shadow" option.
6. Take a screenshot of a maximised window again, using either "Active Window"
or "Window Under Cursor"
7. The resulting screenshot does not have the extra padding like the first
screenshot.
OBSERVED RESULT
Screenshots of maximised windows include extra padding where the window shadow
would be, when the "Include window shadow" option is enabled.
EXPECTED RESULT
Screenshots of maximised windows should not include this padding as there are
no shadows to capture. This was the behaviour of Spectacle up until 24.08.0, so
hopefully it is possible.

ADDITIONAL INFORMATION
I am almost certain this is a regression from 24.05.2, as screenshots that I
took yesterday have the correct dimensions, but I am not 100% certain that the
previous version I was using was 24.05.2. I am using an up-to-date Arch system,
so whatever the last Spectacle release included in stable KDE Gear is the
version I was using :-)
