Describe the bug

The Export from a note to pdf takes a long time. Normally the waiting wheel spins, stops and spins again.
If screensaving starts during that process, the export fails.
If I use "coffee" to prevent screensaving, the process is successful.

To reproduce

1. Go to Share and select pdf
2. Wait until you can share the file
3. If Screensaving starts, the process fails

Expected behavior

The export process should continue successful in the background.

Saber version
