Description Michael 2020-08-06 07:09:28 UTC
After starting the program, the main starting interface develops a graphical anomaly or glitch.  The anomaly "grows" only when I move the mouse.  The effect is like an outline being drawn around the buttons and graphic elements of the interface, and continues over and over again and expands.

Steps to Reproduce:
1.Start LibreOffice.
2.Move the mouse around the screen.
3.Move the mouse around the screen continuously to exaggerate the problem.

Actual Results:
An outline appears around buttons and graphical elements of the UI, and continues to "grow" as the mouse is moved.

Expected Results:
The graphical error should not occur. Note: Disabling the hardware acceleration from safe mode fixes the problem.

Reproducible: Always

User Profile Reset: Yes

OpenGL enabled: Yes

- Does this happen with Skia software rendering (see previous comment)?
- Please post a screenshot of the problem.
- What are the contents of your <cachedir>/skia.log (where on Windows the <cachedir> should be AppData\Roaming\LibreOffice\4\cache)?
Comment 3 Luboš Luňák 2020-08-20 12:30:57 UTC
- Are your graphics drivers reasonably new? Does updating them help?
