1. The background flickering bug remains. When, when opening a new tab, one background is loaded first, and then the one specified in the user’s settings. This can be clearly seen when the video is paused. The more tiles there are in a new tab, the longer the delay between loading the two backgrounds. This sometimes appears in version 7.1.6.1100, where they added "New setting added for the new tab page - switch for daily background image update." And it became a constant problem since version 7.
