Bug#854030: sweethome3d: Consider adding '-Dsun.java2d.opengl=true' startup option

[Alessio Gaeta]

Package: sweethome3d
Version: 5.3+dfsg-2
Severity: wishlist

Dear Maintainer,

SH3D 2D interface is very slow and lagging, at least on my machine (an 8 cores
Intel i7, not exaclty a low-end one). Adding '-Dsun.java2d.opengl=true' to
startup options (in /usr/share/sweethome3d/sweethome3d.sh) made it usable.

I know that OpenGL acceleration is always problematic, and I don't know hot its
support is in OpenJDK (I'm using the Oracle JDK), but OpenGL is already used
for the 3d view, after all, and in a CAD is a must (drawing a wall with the
mouse pointer jumping back and forth is a real pain...).

Thanks you. Regards
