Created attachment 184767 [details] Some buttons in dark mode are invisible in toolbar.
Believe the foreground/background color "sense" for detected dark mode was corrected at 7.4, and certainly for the 7.5 release. 7.3.7 is EOL, please retest with a current 7.4.4 or upcoming 7.5.0 release.
Looks like you are using a icon theme that's not made for dark mode (Colibre). Please use an icon theme that has "dark" in the name, in Tools > Options > LibreOffice > View. Since version 7.4, Colibre also has a dark variant. Thank you!
