Hello, I have a vision screen that glitches out every once in a while and will double-vision my fields, buttons, and windows. I looked over my script and all look fine. Other stations/HMI's dont have any issues. Has anyone ever encountered this? Is there a way to force a refresh of a window between transactions? ![double screen issues](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/7/27e47df12d51dd40b7db835c88467826e55fc6a3.jpeg) ---

This could just be a hardware issue on this one device? ---

Did you find a solution to this? We just started experiencing this after the last software update. It is happening on several different work stations. ---

Same Here....Multiple screens and platforms (7.9 and 8.1) across different plants. It is the same thing. The "shadow" is to the lower right of the original. Yes it could be a hardware issue but the same thing happens on different pieces of hardware. Could be a JAVA issue?? ---

It's much more likely to be a hardware issue, but it is possible it's a bug in native code in the JDK. The _most_ likely cause of strange rendering artifacts in Vision is a bad script running on the main thread and interrupting the painting process. However, that would corrupt any system running the same project equally, rather than affecting only a few machines. ---
