Bug ID: 357754
Summary: Crash in eglCreateImageKHR
Product: kwin
Version: 5.5.2
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: egl
Assignee: kwin-bugs-n...@kde.org
Reporter: fab...@ritter-vogt.de
I accidentially set QT_DEVICE_PIXEL_RATIO=100 when opening a Qt application
that uses OpenGL and kwin_x11 crashes repoducably with the following backtrace
until I kill the application:

AFAICS, in #8, ctx should not be 0x0 when calling eglCreateImageKHR.
With the GLX backend, the application is a huge rectangle, as expected.
Reproducible: Always
Steps to Reproduce:
1. Start kwin_x11 with gdb
2. QT_DEVICE_PIXEL_RATIO=100 marble
