Nice, does the patch also affect already running OpenGL applications?

[KQuickAddons] QtQuickSettings::checkBackend() for fallback to software backend

Fixes very annoying crashes of QtQuick KDE applications:
ksmserver-logout-greeter, krunner (if not running before), and others
occuring when the OpenGL driver stops being available (e.g. on upgrade).

This issue often occurs after upgrading graphic drivers, preventing reboot,
which in turn is needed for the drivers to work and not cause this crash.

No changes are required in the above applications, as they all already use
KQuickAddons::QtQuickSettings::init().

Same problem here on fully updated KDE neon 5.11.4. Have to restart using the
command line each time I want to switch the GPU. Only then can I use the other
video card.

This has been around for quite a while, it should be given higher priority.

Note that if running `/usr/lib//libexec/ksmserver-logout-greeter
--mode logout` it outputs LibGL errors such as unable to use swrast renderer
etc.

same problem here, not only ksmserver-logout-greeter crashes, but also does
konsole, apport and most of the kdeapps. As a temporary fix, I am currently
using bumblebee for gpu offloading

I have upgraded KDE from Kubuntu Backports on Kubuntu 16.04 (amd64) and
experienced same problem. Just switched from Intel to NVIDIA in
nvidia-settings, and now I can't log out because of ksmserver-logout-greeter
crash.

If I switch back to original mode (to Intel), it works as expected. 

Will attach backtrace.

I should also mention that doing it from the other side -  switching from intel
to nvidia profile  - does not generate any crash.
