The white flashing screen in Roblox is often caused by outdated graphics drivers. Keeping your graphics drivers updated can help resolve this issue. Sometimes, older devices have trouble handling certain graphics settings, which can also lead to this problem.
Renderer issues, such as those with Vulkan or D3D11, might be the reason behind the flashing screen. Adjusting the rendering engine settings can often fix this. Another common cause is interference from Discord, especially if you are streaming. Closing both Discord and Roblox can solve the problem.
If none of these solutions work, you might be dealing with a Windows profile glitch. Creating a new Windows profile and then launching Roblox from that new profile can be a potential fix. This step can address any profile-related issues causing the flashing screen.
To troubleshoot effectively, start by updating your graphics drivers and adjusting your graphics settings. If the flashing persists, check for renderer issues and close any running instances of Discord. As a last resort, consider creating a new Windows profile to see if it resolves the issue.
