Description maxlefou 2023-12-21 15:43:26 UTC

SUMMARY
Spectacle doesn't show its interface when started, just showing a freezing picture of what's behind the window instead, like a freezing app. The problem doesn't occur on wayland though.

STEPS TO REPRODUCE
1. Log into a Plasma X11 session
2. launch spectacle (either by command line, icon or the print screen key)

OBSERVED RESULT
The Spectacle window appears but the UI doesn't, resulting in showing a remnant image of what was behind the window before. It also gives the following error on terminal: 
`qrc:/src/Gui/CaptureOptions.qml:44:5: QML CaptureSettingsColumn (parent or ancestor of QQuickLayoutAttached): Binding loop detected for property "minimumWidth"`

EXPECTED RESULT
The spectacle UI should show and work, as it does on Plasma under Wayland

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch with kernel 6.1.68
KDE Plasma Version: 5.27.10
KDE Frameworks Version: 5.113.0
Qt Version: 5.15.11

ADDITIONAL INFORMATION
Only happens on X11. Spectacle behaves correctly on wayland. Though i can't use wayland correctly because nvidia...
Also happens in ver. 23.08.3 and 23.08.4. I cannot try older versions because of changed dependencies.
Sorry if it has been posted already, I have searched but haven't found any similar report...

One more detail: using Spectacle to capture screen using direct keys shortcut (like Meta+PrintScreen to get a specific window) works as intended. Only the Spectacle UI seems affected.

Can you attach a screenshot of what it looks like? You can use spectacle to screenshot itself via a global shortcut or `spectacle -r` on the command line. Or just a phone photo would be fine.

I haven't seen this previously and I can't reproduce it with the 24.01.85 beta version.

Comment 6 Nate Graham 2024-01-09 23:15:28 UTC

Same symptoms as Bug 478387, which seems to have been fixed now. Let's call it the same thing.

Sorry, but it's the contrary, it happens on X11 and not on Wayland. For this, I don't think this is a duplicate, as similar as the symptoms are.
Plus, I'm still having this problem today.

Comment 8 Nate Graham 2024-01-10 21:49:22 UTC

Ok. Well the binding loop you reported is fixed in the upcoming 24.02 version, so perhaps that will turn out to have been the cause.
