SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
On a system with switchable graphics (In my case Vega8/Polaris11), when an application tries to access the discrete graphics card in a wayland session (E.G. running Chrome, running glxinfo), XWayland crashes. Applications no longer can see the discrete card. 

STEPS TO REPRODUCE
1. Run an application that accesses the discrete card (DRI_PRIME=1 glxinfo)


OBSERVED RESULT
XWayland crashes

EXPECTED RESULT
XWayland does not crash.
