Does it work if you disable OpenGl ? -> https://wiki.documentfoundation.org/OpenGL I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the issue is still present
My LibreOffice was already running with OpenGL disabled and showed this problem. I enabled OpenGL and confirmed it still occurred, which it did. However, while in the Options--View menu, I noticed the 'Use Hardware Acceleration' checkbox (which was ticked). When I disabled this, the problem disappears. I confirmed this works with and without OpenGL enabled. So the problem relates to HW accel rather than OpenGL.
I'll guess mark as a duplicate of (awfully long not-resolved) Bug 40534. If you think it's different, feel free to explain and set back to Unconfirmed. *** This bug has been marked as a duplicate of bug 40534 ***
