Regression in v2606: continuous forms redraw/flicker on main form

As soon as I installed Version 2606 (Build 16.0.20131.20012), all of my continuous subforms on parent forms began constantly redrawing and flickering, making the application almost unusable.

Reverting to Version 2605 (Build 16.0.20026.20140) immediately resolved the issue without any changes to the database. I have since disabled automatic updates and am remaining on Version 2605 until this issue is addressed.

Has anyone else experienced this problem with Version 2606? Is this a known bug, or has Microsoft acknowledged the regression?
