Qt Version: 5.12.5
Frameworks Version: 5.64.0
Operating System: Linux 5.3.15-300.fc31.x86_64 x86_64
Distribution: "Fedora release 31 (Thirty One)"

-- Information about the crash:
nvidia proprietary driver version : 440.36
egl-wayland : 1.1.4
libwayland-egl : 1.17.0
nvidia card : rtx 2070
export KWIN_DRM_USE_EGL_STREAMS=1

if I use application launcher, plasma will crash after application launcher closed.

The crash can be reproduced every time.

I have the same backtrace.

QT version: 5.13.2
Frameworks Version: 5.64.0

-- Information about the crash:
nvidia proprietary driver version : 440.36
egl-wayland : 1.1.4
libwayland-egl : 1.17.0
nvidia card : gtx 1060 6GB
export KWIN_DRM_USE_EGL_STREAMS=1


Until this is fixed, setting the env variable QT_QUICK_BACKEND=software works as a workaround for me - of course with a small, but noticeable performance penalty.

Comment 3 David Edmundson 2020-04-24 09:32:18 UTC

Fixed by me in Qt 5.15.0: 4bd13402f0293e85b8dfdf92254e250ac28094c7
