RDM loses focus and becomes unresponsive under wayland/gnome 49

Good Morning,

i'm running RDM v 2026.2.0.6 64 Bit on Fedora 43 (Linux 7.0.12-101.fc43.x86_64) with Gnome 49. Ever since I've started using RDM under Linux I've had the problem that the application sometimes looses focus and becomes unusable. I usually have to close and restart the app.

I'm assuming this has something to do with the incomplete Wayland support that will hopefully remediated via the Avalonia Gui update. However, since the last two updates I've encounter the issue much more frequently and in addition got an error message displayed. Strangely the option to "send error report" doesn't seem to work for me.

Therefor, I though I share a screenshot as well as text of the error message for you to have a look and maybe it is possible with a small fix to resolve this issue under wayland. if it's a bigger issue don't bother. I'll wait for the Avalonia Gui then.

Error message in text:

NullReferenceException - Object reference not set to an instance of an object.

The issue occurred early this morning, I just had one websession open to a remote system.

If you need any further information just let me know. The issue happens quite frequently so I can provide further logs if needed.
