Hello,

thanks for the report. I haven't noticed any performance issues with
Sweethome3d and OpenJDK in the past and I use a rather poor video card
for nowadays standards (Radeon HD 6450 using the Gallium OpenGL
renderer). I haven't tested the Oracle JDK though. We can test your
proposed setting when Stretch is released. I will add it to JAVA_ARGS in
/usr/bin/sweethome3d which seems to be the appropriate place for this
package.

Regards,

Markus
