Uncontrollable flashing and flickering caused by UIGradients

Recently we noticed in an in-development experience as well as a live experience (note: we only experienced these issues on PC) where GuiObjects with UIGradients in them when in movement or when changing size in response to a player’s Viewport changing size are causal to flickering and intense flashing. This is an urgent issue, as we would not like to expose our players to intense flashing without their knowledge.

We have not made changes to the systems that implement these behaviors in many months - in all cases where the UIGradients are moving, we use TweenService to create and play a Tween on the GuiObject that the UIGradient is a child of.

The affected experience in question:

Expected behavior

UIGradients shouldn’t cause flickering. This is dangerous
