Ihor,
I see the same thing as Billy, both with an up-to-date Org main branch
and 9.7.25. Applying his patch fixes the issue.
Note that step 2 fails for me, with the message:
make[1]: emacs-30-vcs: No such file or directory
make[1]: *** [Makefile:64: org-version.el] Error 127
make[1]: Leaving directory '/home/tester/org/org-mode/lisp'
make: *** [mk/targets.mk:128: autoloads] Error 2
Reproduction:
1. cd /path/to/org/git/repo (main branch)
2. git checkout main && git pull origin refs/heads/main
3. make clean && make
4. launch emacs
5. M-x load-theme RET modus-vivendi RET
6. M-x customize-variable RET org-preview-latex-default-process
(set it to dvisvgm)
7. C-x C-f /tmp/bug.org
8. Type in \(x^2=2\)
9. C-c C-x C-l
10. M-x customize-variable RET org-format-latex-options RET
(change :background from default to "Transparent")
11. Redo steps 8-9 on a new equation.
Step 9 will display a white rectangle, step 11 will display the correct image.
