Re: Suddenly very slow in 2D plan view in Ubuntu 16.04
I am having the same problem. The 2D view is extremely slow (at least 1s delay to any user interaction) while 3D runs smoothly. I can remember vaguely that this problem originally was not present, but I don't recall what has changed.
I am using Sweet Home 3D 6.1.2 on KDE SuSe 15.0 on a Ryzen 1700 /Radeon 580.
Maybe it is noteworthy that this is a dual-monitor setup with two 4K screens (i.e. GUI scaling is activated in KDE) and I start with

java -Xms2048m -Xmx2048m -Dcom.eteks.sweethome3d.resolutionScale=2 -Dswing.plaf.metal.controlFont=Dialog-12 -Dswing.plaf.metal.userFont=SansSerif-12 -Dswing.plaf.metal.systemFont=SansSerif-12 -jar /home/paul/bin/SweetHome3D-6.1/SweetHome3D-6.1.2.jar

For comparison, I downloaded and started the portable version of Sweet Home 3D which is just as slow.

Does anyone have a suggestion?
