Description Markus Rathgeb CLA 2019-07-23 16:07:59 EDT 
I tried to use the Eclipse IDE for (I assume years) on KDE Wayland from time to time.
But after one or two starts I switched back to set GDK_BACKEND to x11.

Is Wayland better supported on Gnome then on KDE?
I see several scaling errors e.g. all text that identify the tabs.
Also the package explorer content, the outline content etc. are to big.

There was a fix merged today which addresses some of the double scaling issues on Wayland -- see bug 507020. Please try tomorrow's I-build (nightly build) and see if the issues are fixed. You can find them at: http://download.eclipse.org/eclipse/downloads/

I will test tomorrow and comment here.

There are some issues with KDE Plasma. Can you please let us know the OS you are using? I will check and see how we can fix

I am using Gentoo + the KDE portage tree overlay to get the most recent KDE version.

I will test it this evening or tomorrow.
Comment 5 Sravan Kumar Lakkimsetti CLA 2019-07-25 02:13:19 EDT 
HiDpi is better supported on Gnome on both X11 and Wayland. I would suggest using Gnome as it uses scaling from OS.
Comment 6 Markus Rathgeb CLA 2019-07-25 13:11:17 EDT 
I created a new user to ensure that no specific user settings affect the result.

I used eclipse-SDK-I20190724-1800-linux-gtk-x86_64.tar.gz and tried on a Plasma Wayland session and a Weston Wayland session.

On both session the UI does not look as it should be as soon as a scaling of 2 is set.

What information can I provide to help as good as possible?
Screenshots?
Debug logs?
...

Should I test several environment variables to ensure that no system setting affect the test?

Any news to get Eclipse IDE working correctly with KDE / Plasma on Wayland?
