Adobe xd seems mixed both black and white theme (see the image), I've been searched through the internet and find no such similar problem.
I've installed adobe xd in February 2020 and used it for my project, it was fine. However, I barely used it since then, recently when I open it again and I got the problem. I reinstall and update many times but still look the same.
This is strange we haven't heard this issue before and thanks for sharing the screenshot of your XD interface. We would like to know a few more details to investigate about the issue-
Please share the screenshot of your about XD info page and system info.Would you mind checking the latest update to your graphic card driver?
