Terrain-decoration Bug

[Jo_Lua]

Hello, i am currently working on a system that adds physics to the roblox water (flow mechanics, voxel based) which requires to constantly update a certain terrain area if the player is in range.
Somehow the grass is always blinking when the terrain updates.

Here is a video that shows it:

What i know so far is, setting the the terrain decoration to false fixes the issue…but yea the grass decoration is gone then…

This problem appears in the actual game too. I have this issue since this month
Any idea why that happens?

Is this a temporary glitch that is fixed when you shut down Studio and restart it?
It may be a glitch in your Studio on your computer. Did you try Uninstalling and Installing Studio?

You say it appears in game as well. Are the players able to edit Terrain in your game or does the flashing happen on the grass already in-game?

I did everything you can possibly do to fix roblox/ roblox studio (reinstall, cache cleaning, secret cache cleaning, cookie cleaning…)
I have this bug in the game aswell, not just in the game engine

here is the link to the water physics testing place: waterphysics - Roblox

Terrain Tools are all square brushed, and modifying Terrain causes it to flicker

This issue (or at least the flickering) is caused by an unflagged change that accidentally made it in a couple of weeks ago. We’re working on issuing a fix in a future release. My assumption is both these issues originate from a similar place. I’m trying to reproduce the square brush issue and seem not to be able to on my end. Does this only happen with MaterialVariants? Does the square start at the center of the brush, or does it align with something else? What happens with larger brush sizes…

Please check the following bug report. A fix for the flickering issue will be in next week’s release.
