I'm using the latest stable version of DO and have problems with the display of files and folders, DO on the left, Windows Explorer on the right:
When I switch to the standard theme it's even worse:
In Windows Display settings, what is your DPI scaling set to?
Back in Opus, which fonts and sizes are you using for the Folder Tree and File Display?
DPI scaling is set to 100 %, font is Segoe UI size 9.
Thank you.
I've tried to recreate a similar setup to your screenshots but haven't been able to reproduce the problem so far:
If Preferences / Miscellaneous / Advanced [Information Display]: display_folder_extensions is set to True, try resetting it to False.
If you want, you could send us a config backup so we can try to reproduce the problem with your exact settings. To make one, use Settings > Backup & Restore. Please send it via private message.
Thank you, too.
Strange enough the problem vanished after I had changed the DO language from German to English!
Does the problem come back if you switch back into German?
No, all good now.
