Artifacts of the text are visible, but not some of the characters, until after the page is refreshed. This appears to be part of a general regression on Linux in recent nightlies of rendering/compositing, as some layers of complex pages may not be fully rendered immediately. Reproducible: Always Steps to Reproduce: Even in these text entry fields, simply: 1. Type text 2. As text is typed quickly, some of it is obscured 3. As the screen is refreshed, the text is restored Actual Results: Text is obscured. Expected Results: Text should refresh more quickly as it is updated. I cannot provide a screenshot as GNOME appears to refresh the screen prior to taking the shot.
