Created attachment 124678 [details] screenshot 1) Steps to Reproduce: - Ensure OpenGL is turned off. With OpenGL turned on, the issue disappears. - Use a compositor. - Launch LibreOffice (Writer, Calc, Impress). I did this on a Mate desktop with two different compositors (built-in and Compton). I run Debian Testing. 2) Actual result: The toolbar and status bar separators are out of place. Sometimes they disappear completely. Please see attached screenshot for more details. 3) Expected result: Toolbar and status bar separators stay where they belong. 4) Build & Hardware info: version: 5.1.2.2.0+, build-ID: 1:5.1.2-3 *-display description: VGA compatible controller product: Kaveri [Radeon R7 Graphics] vendor: Advanced Micro Devices, Inc.

Is it duplicate of bug 99446?
@raal: It is well possible, but it is also possible that they are two bugs. When compositor is turned on, I see both this bug and bug 99446. When compositor is turned off, I only see bug 99446.
Whereas bug 99446 appears to have disappeared in 5.2.0.0.alpha1 (Build ID: 902b28a39528b6c92602e9b521a1d0861be1caf9), this bug is still there. Thus no duplicate.
Please let me know if you need any logs from dev version, I will try my best to help in debugging.
I see something similar with the Cinnamon desktop, too. There the toolbar and statusbar separators are in place only in the full screen window. When the window is resized, the position of the separators is not updated, leading to exactly the same image like with Mate and compositor.
This problem seems to be associated with selected desktop themes. For reference, I am using the Albatross theme and see this bug there. When I change the theme to Adwaita, the issue disappears! According to their release notes, this should be fixed in Mate 1.14 (for Cinnamon I don't know), which I unfortunately cannot test right now. However, I guess it is safe to consider this bug as resolved.
