Description Quinten Kock 2022-12-31 01:08:22 UTC

Application: systemsettings (5.26.4)

Qt Version: 5.15.7
Frameworks Version: 5.101.0
Operating System: Linux 6.0.15-300.fc37.x86_64 x86_64
Windowing System: Wayland
Distribution: Fedora Linux 37 (KDE Plasma)
DrKonqi: 5.26.4 [KCrashBackend]

-- Information about the crash:
I changed my scaling setting from 150% to 100%, hit apply, and then System Settings crashed. (It did however succesfully apply the setting).

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: System Settings (systemsettings), signal: Aborted

Looks same as https://bugs.kde.org/show_bug.cgi?id=450489

Not sure, because this was a systemsettings crash. Plasma itself continued to run as usual.

Crashing in the Intel graphics drivers. Please file a bug for the developers; see https://docs.mesa3d.org/bugs.html. Thanks!

New crash information added by DrKonqi

systemsettings (5.27.2) using Qt 5.15.8

I changed the scale of one of my two monitors and lcosed the window. A dialog showed asking me if I wanted to apply the changes and clicked "Yes", then it crashed

Comment 5 Nate Graham 2023-03-01 15:02:02 UTC

That's different Luca. Looks like Bug 461581.

Comment 6 Luca Bacci 2023-03-01 17:11:31 UTC

Ouch, yes!! I should have posted in BUG 461581 

I'll see if I can reproduce with a debug build of libkscreen and post there a new stacktrace

Thank you!
