Dreamweaver 21.7 code view UI (text, scrollbar, etc.) become unusably massive when creating new file

Dreamweaver 21.7 on Windows 10 rig.

No add-ons or plugins. I run a lean code editor.

First- been a DW user for a very long time (nearly 2 decades). I know all the preference reset hacks. Already tried them. This is a bonafide new bug, especially since it's been a month of Sundays since Adobe cared about DW and now suddenly it's not functioning properly after a new update.

When going to "File -> New -> *select any document type*" the new file appears, as expected, but the code editor font is so large, only a handful of 'words' in a string fit per line before wrapping. Additionally, the scrollbar becomes massive (about ~50px wide) as well as the line numbers being FUBAR too.

If you close DW and restart, the UI becomes normalized and usable again. However, if you create a new file again, same issue all over again.

If you go to "View -> Code View Options -> *select either 'Decrease Font' or 'Restore Font Size'*" to correct without restarting DW, the font sizes do get smaller as intended, but the scrollbar remains massive. Same outcome when using keyboard shortcuts as well. IF you do reduce font size either or these two ways, and then also restart DW, the file loads illegibly too small (oposite problem).

This really looks like a Windows zoom or DPI scaling issue, rather than a core Dreamweaver bug. A few quick things that are worth checking :

Windows Magnifier: Even if it was enabled briefly, it can leave DPI in a weird state. Try Win + Esc, then also check Settings → Accessibility → Magnifier and make sure it's fully disabled.
Display scaling: Go to Settings → System → Display. Check the scaling value (100% or a stable value is best). If you're using multiple monitors, try launching Dreamweaver with just one screen enabled.
High DPI settings for Dreamweaver: Right-click dreamweaver.exe → Properties → Compatibility → Change high DPI settings. Try enabling "Override high DPI scaling behavior" and test with Application (and, if needed, System (Enhanced)).
Avoid adjusting font size inside DW while testing: After restarting DW, create a new file and don't use Decrease Font or Restore Font Size yet. If DPI is already off, those commands can make the mismatch worse.
Check for accidental zoom input: Things like Ctrl + mouse wheel, trackpads, or mouse utility software can sometimes trigger zoom behavior that DW doesn't handle well.

The combination of huge font, oversized scrollbar, broken line numbers, and everything returning to normal after a restart seams very typical of a DPI recalculation issue on Windows (worth on W10).

We can't see attached images. The Viewer is broken.

And it doesn't look like it will be fixed before the new forum platform launch in mid-January.

It does sound like a low memory issue.

I use keyboard shortcuts to make things bigger & smaller.

Ctrl++ = bigger

Ctrl+0 (zero) = normal,

Ctrl+- (minus) = smaller,

Does it continue after saving untitled document (Ctrl+S) to your local site folder?
