How do you Stop this Jittery Text Back and Fourth Movement when Resizing your Gui???
My main question is this normal because I’m going to use the tween service to slowy resize the main gui and i’m wondering if this will happen when doing this and how to prevent but if it is a ROBLOX Studio glitch I would like to know.
Are you using TextScaled or Scale-based sizing in your GuiObjects? Since you are likely resizing some higher-layer GuiObject (parent or parent of a parent etc.), the pixel size/position of the Text GuiObjects will jitter because they are trying to recompute their exact size/position with respect to their family GuiObjects. For example, if you resize the width of a parent frame 1 pixel, a TextLabel may remain static visually, but if you add 2 pixels, and the TextLabel is centered, it may move 1 pixel to the right. The jittering is a symptom of continuous resizing between even and odd pixel AbsoluteSize.
One way to avoid this is to fade Text GuiObjects out during calls to TweenService methods or simply use offset-based Text GuiObjects that are programmatically sized/positioned using fractions of their parent GuiObjects (might not be feasible). Sorry this is happening! 
Thanks for explaining why this was happening and a way to fix it sorta of I will just use the fade way but thanks so much.
Another annoying option that might prevent annoying jittering is to use ImageLabels with a custom font. However, this is a lot of work and probably not worth it unless you are creating a game that you think needs an aesthetic boost.
Yes I just tried what you said before you said it because I looked this up but couldn’t find anything but then I looked a bit harder and found something similiar to what you said thanks a lot though.
