Visual Studio 2022 Theme Malfunction

The Dark theme normally applies to all editor windows in Visual Studio.However, the window shown in your screenshot is the SSIS designer, not the code editor.The SSIS designer doesn’t fully support dark mode, so parts of it (like the design surface) stay white.There’s no real issue. The dark theme works fine in code files like .cs, .sql, or .xml.

If you still want to try resetting your Visual Studio settings, you can do it by closing Visual Studio and running the following command inRun (Win + R) or Command Prompt:
devenv /resetsettings

Unfortunately comment is not working. Was looking for Visual Studio 2026 fix as my 2022 SSIS does work, but I have no idea how it works. My theme is set to dark and this is how my SSIS packages look, dark mode.

Visual Studio 2022 Dark Mode for SSIS

Maybe I found the theme file somewhere and edited it directly, but it's been over a year.

The main issue with Dark Theme here is the annotation on the arrows.

So, for anyone facing the same issue with Visual Studio's Dark Theme and doesn't want to get Flashbanged by the Light Theme, you can download a Free Extension called "Visual Studio Theme Pack" and you can choose whatever theme that suits you and has no white text.

Because apparently, the problem is that whatever theme you choose doesn't change the Background of the Design Canvas, but it only affects the text.

Also, you might need to close the .dtsx window and reopen it so that the chosen theme reflects on the Design Canvas.
