Hello,
after creating a DEM (or ortho) and choosing it in the workspace pane, the UI stops working, i.e. icon disappear, the DEM (or ortho) just does not appear.
If I click again on tie points or dense cloud, and then again on DEM (or ortho), the DEM (or ortho) appears, but no interaction is possible with the image. Icons continue gone.
Please check image.
My system specifications also as image.
