Bug ID: 437652
Summary: Spectacle sometimes fails to take a screenshot under
Wayland
Product: Spectacle
Version: 21.04.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: General
Assignee: m...@baloneygeek.com
Reporter: m...@dblsaiko.net
CC: k...@david-redondo.de
Target Milestone: ---
SUMMARY
Spectacle sometimes fails to take a screenshot under Wayland, I'm not sure what
causes it but if it fails once, it never works again until a restart (probably
logout/login too, but I don't do that under Wayland because of bug 433293).
This is using a "normal" KDE setup with Kwin.
STEPS TO REPRODUCE
1. ???
2. Open Spectacle
3. Take a screenshot (with any of the screenshot modes)
OBSERVED RESULT
Spectacle says "Could not take a screenshot. Please report this bug here: <link
to bug tracker>". It also prints the following to stdout every time I try
taking a screenshot:
libpng error: Read Error
QPixmap::scaled: Pixmap is a null pixmap
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()
EXPECTED RESULT
A screenshot is taken and appears in the preview.
