Re: Suddenly very slow in 2D plan view in Ubuntu 16.04
Hello,

I have a similar problem on yet another Linux config, with Manjaro 18.0 and xfce desktop. The 3D view works pretty smoothly, but drawing in the 2D view is sluggish. Same in SH3D 6.1.2 and 5.7 for me.

Actually most of the GUI, except for inside the 3D view, seems sluggish. E.g. Edit or Preferences windows take about a second to pop up.

Meanwhile the CPU and RAM don't seem to be maxing out at all...

This is the first time I'm using SH3D so can't compare to a previous situation.

some system info:

Intel(R) Core(TM)2 Duo CPU     P8600  @ 2.40GHz
4 Gb RAM
00:02.1 Display controller [0380]: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a43] (rev 07)
	Subsystem: Dell Mobile 4 Series Chipset Integrated Graphics Controller [1028:0233]

OpenGL version string: 2.1 Mesa 19.0.3
OpenGL shading language version string: 1.20

Surely not the latest, but too old?

and the Java version:

openjdk version "1.8.0_212"
OpenJDK Runtime Environment (build 1.8.0_212-b01)
OpenJDK 64-Bit Server VM (build 25.212-b01, mixed mode

Perhaps installing a different Java version would help? That does not look straightforward though as it would break dependencies for other programs; and it may not be worth the trouble...?

In any case, it's still fairly usable for me; many thanks to Emmanuel and any other contributors for this program!
