1520092 - Drafting email with tables in gmail causes screen to flicker

Status: RESOLVED DUPLICATE of bug 1519541

(Core :: Layout, defect)

Description

Steps to Reproduce:

1. Create an email with a table in gmail and send to yourself
2. Copy and paste another table in the reply (can be same table as step 1) and send to yourself
3. Click to forward the email and screen flickers

I've attached screen captures of me pressing the forward button and the screen flickering. In my original case, I had to start scrolling to get the flickering but in this smaller test case it appears once I start drafting an email.

In Chrome the screen recording shows that everything scrolls smoothly as expected.

Vicky, if you update Nightly to today's version, do you still see this issue? It should be fixed now but I'd love an extra verification. Thanks!
