Description
Darcy Beurle
Can you please try if Eclipse 4.5 with GTK2 causes same problem as Eclipse 4.4? No one will patch 4.4, but it would be good to know what exactly is the root cause. Eclipse 4.5 uses GTK3 by default, 4.4 uses GTK2, but you can enforce GTK2 by setting env. variable before starting Eclipse: SWT_GTK3=0 (In reply to Andrey Loskutov from comment #1) > Can you please try if Eclipse 4.5 with GTK2 causes same problem as Eclipse > 4.4?

I'm using HiDPI screens on 4.4 and it seems to use GTK3 as I get the rough scrolling and the dialog boxes are scaled. The GTK2 appears tiny on my system. I'm trying 4.5 now with GTK2. Should I try 4.4 with GTK2 instead?

But yes, in this case you should switch 4.4 to GTK2 too. BTW please check your 4.4 eclipse.ini file - if someone changed the launcher arguments to use gtk2? It's --launcher.GTK_version option.

Weird. I have 3 eclipse.ini files locations: (locate eclipse.ini) /etc/eclipse.ini ~/.eclipse/org.eclipse.platform_793567567_linux_gtk_x86_64/configuration/eclipse.ini.ignored /usr/lib64/eclipse/eclipse.ini The first and last say --launcher.GTK_version 3 - maybe this is a packaging addition for F22? I'll launch 4.4 now with GTK2 and report back.

Launching with GTK2 stops the swapping on 4.4. The problem seems to still exist with resent Oxygen: Eclipse Java EE IDE for Web Developers. Version: Oxygen.2 Release (4.7.2) Build id: 20171218-0600 OS: Ubuntu 17.10 $ java -version openjdk version "1.8.0_151" OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.17.10.2-b12) OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode) Building Java (for example when I update Maven deps) project consumes about 2GB+ of RAM - and that is never reclaimed back. My eclipse.ini contains this: -Xms256m -Xmx1024m So RSS should be limited close to 1GB - yet single build puts it close to 3GB. I've also noticed that problem only exists (at least as prominent) when GTK3 is enabled. If I switch to GTK2 there is not much memory consumption growth. *** This bug has been marked as a duplicate of bug 533995 *** |
