It will be a huge help if you can tell us the exact steps that lead up to your bug happening. Does it happen every time or just sometimes?
If you can manage to get a screenshot, or even better a video (if you’re a streamer type) of the bug, that will really help us track it down. Please upload the screenshot or video somewhere we can see it, and put the link in your bug report.
Please also tell us:
- Your Windows version
- Is it 64 or 32 bit?
- Your make and model of video card
- The amount of RAM in your PC
