Screenshot #1:
On opening a project in v1.3 (just installed minutes ago after upgrading from 1.2) only a small portion of the model view is displayed/updated. I can rotate the view, but only that small portion in the middle is updated.
Screenshot #2:
Immediately after taking a screenshot, moving the mouse causes the view to be refreshed and all is visible again.
Screenshot #3:
If i don't take a screenshot straight away, and rotate the 3d view, only the central 'viewport' is updated
Screenshot #4:
Immediately after taking a screenshot, moving the mouse causes the view to be refreshed and all is visible again.
