Description Tobias 2020-10-13 15:14:55 UTC
The performance of LibreOffice increasing, if there is a image visible.

Especially there is a image on the screen in the Writer document, the performance of writing of removing a text is very awful. But, if I scroll down or up in the document so the image isn't visible on the screen but still in the document, the performance is perfect!

Steps to Reproduce:
1.Insert a image from memory with 'Strg' + 'V'
2.Try to write a text while the image is visible on screen
3.Try to write a text while the image is in the document, but not on screen

Actual Results:
Low performance

Expected Results:
Normal performance

Reproducible: Always

User Profile Reset: Yes

OpenGL enabled: Yes

Additional Info:
Same results, if there is OpenGl on or off, Java RE on or off, image compressed or not

This should be solved with 7.0.5
