***
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.
