Describe the bug
When Reconstruction Viewer is opened alongside an active SNT instance, the entire GUI slows down dramatically to the point of being nearly unusable. This only appears to affect Linux distributions (I don't know about mac, as I do not own one). I have encountered this both on my Manjaro KDE plasma box with a discrete GPU (GTX 1080), and on my Fedora 34 Workstation laptop with intel integrated graphics. Windows is not affected, at least perceptually...

The standalone Reconstruction Viewer is not affected, unless an SNT instance is opened after starting the viewer, or if an SNT instance was closed prior to starting viewer.

To Reproduce
Steps to reproduce the behavior:

  1. Start SNT
  2. Open Reconstruction Viewer (either standalone or from the SNT dialog's 3D tab)

or

  1. Open standalone Reconstruction Viewer
  2. Start SNT

or

  1. Start SNT
  2. Close SNT
  3. open standalone Reconstruction Viewer

I noticed this too. Really frustrating. What I had never noticed is that the last sequence can also trigger it.
Things we could try:

  1. If we suppress all of the legacy 3D Viewer calls in SNTUI, does it still happen (i.e., suppress the "Legacy 3D Viewer" widget). If I recall correctly, there are some static calls to jogl code. I guess another way to test this would be to see if opening the legacy 3D viewer also degrades things
  2. Are resources from SNTService /SNTUtils not being disposed properly?
