Are you running a fairly low-end video card or a "built-in" video card on a laptop? Then try this...
- On the Help menu, choose Accelerated Graphics, then Disable
- Close / Restart Tableau (Important!)
- Try again
If that doesn't solve it, you might want to re-enable accelerated graphics as it'll give you a perf boost.
Thanks for the suggestion! Unfortunately, disabling Accelerated graphics did not help.
My laptop is using the default video card in my HP laptop, although this problem is showing up on other PCs in the company as well.
