Created attachment 261885 [details] comparison mars.2 and neon I tested Neon RC1 as target for our RCP application. It seems there is a slight difference between the two, as visible in the attached screenshot. Scaling of the icons is /not/ the issue. The problem is, that the minimize/maximize buttons are wrapped to a separate toolbar on Neon, where in Mars.2 (and all previous versions) those buttons have been next to the tabs. Since this does not happen to the IDE views, I suspect that something in an area changed that is not obvious to me... What we're showing in our application is "extends EditorPart implements ISaveablePart2"
I notice there is also a difference in the size of the icons. This Looks like an SWT Issue. Could you please tell us which Linux and which GTK version are you using? https://coffeeorientedprogramming.wordpress.com/2014/10/27/how-to-tell-if-you-are-running-eclipse-on-gtk2-or-on-gtk3/

Does this happen if you run with SWT_GTK3=0 environment variable?
Nope, with GTK2 everything seems as usual.

Are you on KDE? Which GTK+ theme are you using? Can you try to use Adwaita?
Cinnamon here. Theme is zukitwo.
and, as stated in the original comment, this happens with our RCP application, but not with the NEON IDE itself - which seems strange...
same happens with adwaita

Arggh, I've missed that! This would indicate that is not an SWT issue, but then I can't get why it is broken only on GTK3. Are you sure they both are using same Neon platform libraries?

Hmm, let's see whether I can get Gnome running here :D > > (In reply to Markus Duft from comment #9) > > and, as stated in the original comment, this happens with our RCP > > application, but not with the NEON IDE itself - which seems strange... > > Arggh, I've missed that!

The GTK2/3 tryouts 100% only differ by the environment variable to turn off GTK3.
Happens with Gnome 3 session too. phew. :)
Created attachment 262111 [details] E4 Model Spy of application (welcome screen) I just noticed that this also happens with the welcome screen. we're using a plain workbench intro for this... I also included the E4 model spy to give you some overview of the application model - no big surprises from my POV. If you need to know more, please tell me.

Created attachment 272563 [details] Eclipse 3.9.2 / STS on OSX I'm seeing the same issue on OSX 10.13.3.
(In reply to Steve Hunter from comment #18) > Created attachment 272563 [details] > Eclipse 3.9.2 / STS on OSX > > I'm seeing the same issue on OSX 10.13.3. Unlikely it's a Linux GTK issue or even SWT, then. Moving to Platform UI for comment.
The latest comments and duplicates seem more to be bug 389833 (which is not Linux specific, happens at least on Windows) than the original issue reported here.
Rolf, please check if that is still valid.
The original issue is reported on Linux, and shows a difference between GTK2 and GTK3. I am not on Linux, so I cannot validate. Though, this could be a duplicate of Bug 499215. w.r.t. the duplicates they are probably not related, as they are about the 'double' bars in top of the editor area. That should be Bug 389833 (stalebug) and/or Bug 495230.
Thanks Rolf, I cannot replicate on Linux with Eclipse SDK Version: 2020-09 (4.17) Build id: I20200610-1800 OS: Linux, v.5.4.0-37-generic, x86_64 / gtk 3.24.18, WebKit 2.28.2 Java version: 1.8.0_252 So this might be fixed via another bug as Rolf indicated. Markus, please reopen if you still see this with 2020-06.
