Really? I'm using their IDEs on Fedora 35 with Wayland. Seems to be working fine.

Now disable XWayland and try again

No chance of that, everything they do is in Java...

It's actually Kotlin aka "I Can't Believe It's Not Java!"

Makes sense given that Kotlin is their own in-house language.

To be fair, Wayland is still new (compared to how long Java has existed), and Java/OpenJDK may improve support in the future.

Wayland is almost 15 years old by now, and it's on track to be enabled by default on most distros as well.

Java is 26 years old.

The first distro to use Wayland by default was Hannah Montana Linux, 10 years ago. Only recently have more widespread distros started using Wayland by default.

Java is old, and Wayland is comparatively new.

there also isn't a reason for them to use it xwayland works fine for the usecase.

I hope they support wayland natively but its just not necessary atm.

XWayland does not work fine for multi-monitor setups with mixed dpi. All XWayland applications will look blurry and there is no intention to fix this for XWayland because its already considered obsolete.

x11 has problems this is known. not moving to wayland isn't a regression its just maintenance of the status quo.
