How to fix black bars covering dropdown headers?

I was able to get BrawlCrate (ver. 0.36) working on Bottles 51.5 by copying the folder into the drive_c folder and installing Wine Mono. However, when it boots, there are large black or white bars covering various headers in the application, making it basically impossible to read what settings are being changed. The program still runs and can be edited like normal, but the bars make it extremely difficult to see what I’m editing. Is there a setting, dependency, or instruction I’m supposed to give it to make these properly visible again?
