3d Viewer exports wrong OpenGL canvas

[Seth Hillbrand]

When using 3d Viewer, export as JPG or export as PNG will export the last OpenGL canvas that has refreshed.

To reproduce:
1) Open a demo project (e.g. PIC Programmer)
2) Open eeschema
3) Open pcbnew
4) Open 3d-viewer
5) Switch to eeschema (Alt-Tab) and zoom in one step
6) Alt-Tab back to 3d-viewer
7) Without changing anything in 3d-viewer, choose File->Export Current View as JPG

This will export an image of the schematic rather than the 3d-viewer

If you rotate the 3d view and/or zoom in, then export the 3d image will be exported

I cannot duplicate this on windows. This appears to be another linux specific bug.

[Seth Hillbrand (sethh)]

OK, good to know. Curious though. Maybe Windows does an additional GL refresh when activating the 3d viewer
