Not sure whats the cause, but on all roblox games, some users are having graphical issues such as blue screens covering sections of the viewport or images not being removed like the old Windows dragging errors window across the screen to make art kind of bug.
How often does the bug happen (Everytime/sometimes/rarely)? They say every time, for every game
Would a screenshot or video help describe it to someone? If so, post one.
For graphics bugs, it is sometimes helpful to know your system specs, especially graphics card. Mac El Capiton: ATI Radeon HD 4670 256 MB Windows 8? Dell: Graphics card: TBD
When did the bug start happening? If we can tie it to a specific release that helps us figure out what we broke. Today’s update
This might be related to an issue earlier today. This might still affect already running games. Also, if they are running mobile, they might need to close the Roblox app and then restart it. Hope this helps.
mobile = Win10 App, Xbox, iOs, and Android. So mobile, console, and one version of desktop.
