Man, you've got me scratching my head. I did learn a lot because of you 😉.
Anyway, I made a temporary test bottle, screwed the DPI badly, and used the following command in terminal to set things back to normal. Just replace "a_bottle" by the name of the bottle (usually found in ~/.cxoffice).
echo -e "[HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Hardware Profiles\\Current\\Software\\Fonts]\n\"LogPixels\"=dword:60\n" | ~/cxoffice/bin/wine --bottle "a_bottle" regedit -
It worked for me, so I guess that should do it for you too. I know I'll make a note of that code, because I don't know if I can come up with it again! 😋 DONT REMOVE THE "-" AT THE END OF THE CODE, it's usefull.
Edit: Not having seen your last post, maybe you've changed the resolution to a huge resolution while "blindly clicking", so if your DPI is normal, try:
~/cxoffice/bin/wine --bottle "test" explorer /desktop=default,1024x768 winecfg.exe
That should get you the winecfg windows in a "normal" sized window which would allow you to undo the fun you've made for yourself. Anyway, these two code segments, in order, is the best I can come up with. If this doesn't work, well, you're knee deep in it... Unless some kind Codeweaver ninja takes pity on you.
Good Luck!
