Sorry that you are seeing this issue. Thank you for the screenshots.
I just ran a quick check on DBreaver 22.0.4 and do not see the reported problem with Dark theme.
1. Do you see the issue in a fresh new workspace as well?
2. What update are you referring to? Windows or DBreaver? Can you please check if any specific/custom OS theme is set? Try switching to a different theme like Windows Classic to check if it helps.
If you are still seeing the issue, then please share the DBreaver version, Windows OS theme details and the .log file located at workspace dir/.metadata/.log (rename the extension to .txt and attach it here) to help us investigate further.
