3D image occasionally disappears when rotating/scrolling #233

Closed ilya747 closed 2 years ago

ilya747 commented 4 years ago

Long story short

3D visualisation disappears occasionally when rotated with the left mouse button. It vanished completely when I tried to magnify it by scrolling the wheel

Expected behaviour

Image can be rotated and magnified easily using the mouse. The same as it works in SPARC nerve activity predictor.

Actual behaviour

Image disappears. Occasionally or completely. Sometimes I could get it back by clicking the white button on the top-right, and sometimes I had to restart the node.

Steps to reproduce

Open "3DVisualization of EM-Neuro". Double-click "3d-viewer-gpu". Open the image full screen. Start it (action potential travels), then stop. Rotate the visualisation and magnify it using the mouse. Image disappears. PS - I'm a member of TeamBlack, but I wasn't able to add a black "Feedback" label to the issue (I accessed GitHub through the link in the osparc interface).
