Right today my favourite development environment JetBrains Rider stopped working after updating to the current 2019.2 version:
After starting the application a blank screen (normally with the list of recent projects to open) showed up.
I checked my Windows Box, but it had no problems with the current release. It worked like a charm.
So this was Linux specfic. My workstation runs Fedora 30 and so I started researching. I found out that under X I could set
export _JAVA_AWT_WM_REPARENTING=1

So there are a couple of articles on the internet regarding this, mostly related on how to configure systemd to set this variable in the XWayland session for a specific application.
That sounded too complex for me for such a small change.
But then I noticed that JetBrains Rider itself has a configuration file in the current base directory:
That looked like it would work! So I modified it as follows:
And then I started Rider like always via Gnome under Wayland:
