SUMMARY Underscores display as spaces in the window title bar. Haven't noticed this happening elsewhere like when alt tabbing for example. Easily reproduced with any program that puts the current file/directory in the title.

Cannot reproduce in Dolphin by creating a folder named "hello_foo" and then entering it. What program is it happening in? What window decoration style are you using?
Seems to be any program for me, including dolphin. Using breeze decorations. Looks like underscores are fine on oxygen or plastik.
Can you attach a screen recording of you reproducing the issue in Dolphin by creating a folder named hello_foo and entering it? Thanks!
Created attachment 162353 [details] Demonstration of the issue
Added a video. I should have mentioned before that this only started happening recently.
Well that is strange indeed. I cannot reproduce it when I do the exact same thing.
What font (and font size) are you using? Are you using any scaling?
I use DejaVu sans size 8, no scaling. Tried setting the window title size to 10 in system settings -> appearance -> fonts, and the underscores show up now.
