Suddenly very slow in 2D plan view in Ubuntu 16.04
Hi Folks,

running SH3D on Ubuntu 16.04 was perfectly fast in 2D and 3D about 2 months ago.

Now I started a new project and drawing the very fist wall in 2D is awfull - it takes the wall more than a second to follow the curser. There is no other project open and the wall is the very first object to be drawn - no background - nothing.

I have created a few rooms, which was painfull and dropped a table inside - again taking seconds of delay. Funny enough, if I then go to 3D view, I can rotate, zoom etc. in all directions very fast - it is following the mouse with no delay.....

When I open my old project from 2 months ago, I have now the same effect - long delay in 2D, very fast in 3D. As said, this wasn't the case 2 months ago.

I am using AMD graphics card with latest AMDGPU-pro driver but I would expect that to effect more the 3D performance

Does anybody have an idea?

Many thanks for any help
Klaus
