Also i didn't try the Gnome-based version, was the one you tried Gnome or KDE? Kostas I had KDE only that worked ok but the IDE of lazarus had issues as i told . I deleted Nobara and so the issues with Lazarus are also deleted :-) As a sidenote ... i often read NoBra instead of Nobara and thats my own issue :-) Good night!

Gtk2 works fine with Wayland using XWayland (basically a rootless Xorg that uses Wayland to manage windows) which pretty much all desktop environments ship and support (and AFAIK there are no plans in the foreseeable future for XWayland to be dropped). In fact when i tried a Gtk2 program under KDE Wayland on a small laptop even scaling worked as expected (KDE allows X11 programs to handle scaling themselves instead of having the compositor scale the windows as a bitmap). There is some functionality that is not supported because Wayland itself doesn't support it - e.g., IIRC you can't change the cursor's position and i think trying to grab a screenshot gives you a black image - but that'd affect toolkits that use Wayland directly too. Do distros that use Wayland by default still include GTK2 applications? The stable version of GIMP is still using Gtk2 and i think this is included by distros that use Wayland by default.

The X11 client is needed since there are way(!) too much apps that require X and which cannot be ported to wayland without major rewrites..
