Bug ID: 423862 Summary: Crash on KWin windowed mode toggle to fullscreen Product: konsole Version: unspecified Platform: Compiled Sources OS: Linux Status: REPORTED Keywords: drkonqi Severity: crash Priority: NOR Component: general Assignee: konsole-de...@kde.org Reporter: rjvber...@gmail.com Target Milestone: --- Application: konsole (18.11.70) (Compiled from sources) Qt Version: 5.9.8 Frameworks Version: 5.60.0 Operating System: Linux 4.14.23-ck1-mainline-core2-rjvb x86_64 Windowing system: Wayland Distribution: Ubuntu 14.04.6 LTS -- Information about the crash: - What I was doing when the application crashed: Testing kwin_wayland (5.13.3) in windowed mode under X11. I get this crash systematically when I toggle the window fullscreen (via the WM, or even change its size). It happens with Qt 5.9.8 and Qt 5.12.6 . I don't see in the backtrace exactly how this is a KWin bug (and not one in Qt) but I'm reporting it here because it's KWin that triggers the bug - Unusual behaviour I noticed: Just before the application crashes I notice a reduction in font size, as if the DPI setting changed (it's set to 86DPI in the "parent" X11 session) The crash can be reproduced every time. -- Backtrace: Application: Konsole (konsole), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
