Can I get you to go ahead and file a bug report. You can use the zip file you put on dropbox. Use the Report a link option at the top of the page. When you fill out the form, please reference this forum post. Also you will get a confirmation email. That email has a Case ID in the subject. Please post that back here, then I can ping the engineers to look at it.
The overlay rectangle is there, it’s just shifted down and to the right, like it’s centered on the top left corner at the center of the screen. You can click along the right and bottom edges and see where the clicks stop flowing through.
Once I have the CaseID I can go to Engineering with the problem. Sooner is better.
