CanvasGroups randomly going extremely blurry

,

Hi! I’m using Fusion to make a menu for my game. For the past month, everything has been working as it should, but recently (specifically after the newest roblox studio update), all the menus in my game suddenly went “blurry.”

Here is what a small portion of my text looks like: (you can’t really see it in the screenshot :sob:)

I’m guessing this is coming from CanvasGroups, since when I convert everything into a regular frame it works fine.

Sadly my UI was kind of built around some of the functionality of CanvasGroups (clipping on uicorners, specifically), so I can’t really just change it to normal frames without it being a struggle.

My task manager doesn’t show anything alarming, my Roblox Studio editor level quality is at 21, and my in-game graphics quality is at 10. I’ve also tried re-installing, and restarting Roblox Studio. Does anyone have a solution to this problem? Thanks!

Note: It works perfectly fine inside of the roblox player, so it’s probably an issue with studio

Hey @metatablesnow!

This definitely looks like a recent regression in Roblox Studio regarding how CanvasGroups handle text rendering and clipping, especially after the latest update.

a few temporary workarounds you could try:

  • Force GroupTransparency to 1 and see if that sharpens the text again.
  • Avoid using ClipsDescendants = true on CanvasGroups, as that seems to be triggering visual artifacts.
  • Temporarily replace the CanvasGroup with a Frame using ZIndexBehavior = Global if your layout allows for it.

Additionally, I strongly recommend submitting this as an official bug report under #bug-reports:engine-bugs. :lady_beetle:

After investigating it more its caused when a you parent a CanvasGroup to a frame parented to a CanvasGroup, I’ll try and replace that frame with another CanvasGroup for now. Thank you, I’ll file a bug report about this, if there isnt one already.
