Question 1

Why does draw.io desktop not show update notifications or prompts after selecting 'Search for updates'?

Accepted Answer

This was a bug in draw.io desktop version 30.0.0, where the update check did not display available updates and the app updated silently on exit without asking. Upgrade to version 30.0.1 or later to restore proper update notifications and prompts. You can download the latest package from the official website. After updating, the 'Search for updates' menu will show a prompt when a new version is available, allowing you to accept or decline the update.

Question 2

How do I fix the draw.io From Text dialog not focusing its text box when opened from search?

Accepted Answer

Upgrade to draw.io Desktop 32.4.1 or later. In affected versions (confirmed through 32.3.0), pressing Enter or Ctrl+Enter from the search dropdown moves focus back to the diagram, so keystrokes and Tab do not work in the From Text dialog. As a workaround, press `/`, type `from`, use the Down or Up arrow key to highlight `From Text...`, then press Enter. The dialog opens with the cursor in the text box. Version 32.4.1 also fixes Tab focus escaping the dialog.

Question 3

Why is drawio CLI PNG export low quality or blurry for diagrams with LaTeX (e.g., '+' renders as '-')?

Accepted Answer

This is a regression in drawio-desktop 30.0.0 affecting CLI exports (`drawio --export --format png`) of diagrams containing LaTeX; GUI export is unaffected. Fixes/workarounds:

1. **Upgrade to 30.0.1 or later** — the maintainer indicated the issue is addressed in this release.
2. **Downgrade to 29.7.9** — confirmed by the reporter to not reproduce the bug.
3. **Increase export scale** — add the `--scale` flag to raise output resolution, e.g.:
   `drawio --export --format png --scale 2 --border 4 --output example.png example.drawio`
   (try `--scale 4` if details like '+' signs in LaTeX math are still illegible).

Note: 30.0.0 also causes LaTeX equations to render larger than in the GUI, so equations may overflow their shapes in CLI exports until you upgrade.

Question 4

How do I change the background color when the color picker opens behind the Page Setup dialog in draw.io Desktop 30?

Accepted Answer

This is a dialog layering bug in draw.io Desktop 30.0.0 on Windows/Linux: the color picker opens behind Page Setup, so clicking it closes the top dialog. As a workaround, go to File → Page Setup → Background → Fill color, click the color input field, type a color code such as `#00FF00` using the keyboard, and press Enter. Do not click inside the floating color picker. Apply/save the Page Setup dialog afterward.

Question 5

How do I stop the draw.io color picker from staying open and applying colors to other objects?

Accepted Answer

Upgrade draw.io Desktop to v30.0.0 or later; this release partially fixes the persistent color-picker behavior introduced in v29.7.9. As a workaround on v29.x, manually close the color picker immediately after selecting a color and avoid clicking other shapes while it remains open. If the font-color picker still behaves incorrectly after upgrading, close it manually after each use.
