All of Wayland is based on EGL. What you are referring to are EGLStreams vs GBM which are both libraries using EGL. Nvidia drivers now support GBM for all supported GPUs via a support library that comes with the driver (libnvidia-egl-gbm https://download.nvidia.com/XFree86/Linux-x86_64/510.39.01/README/gbm.html). There should be no difference in the GPU generation used.
@Zamundaaa @mnglw xorg Apps don't crash when the compositor crashes, you can just switch out compositors/window managers. But xorg Apps crash when the xserver is crashing
@klangcola I'm not commenting on whether ot should be a show stopper or not. Just that it will eventually come also for non-Qt apps with MRs from KDE contributors to other projects.
@klangcola @mnglw there are MRs to GTK, wlroots and SDL but the applications/framework will merge and publish the fix at their own release schedule

For troubleshooting, I recommend
For trouble shooting recommend https://community.kde.org/Plasma/Wayland/Nvidia, checking whether all kwin backends are installed (kwin-wayland-backend-* on Ubuntu). Sometimes there's also a problem with the missing OpenGL backends of Qt. An easy check to see whether there is a problem with the proprietary driver is to try out whether the problem also exists using nouveau.
