Bug ID: 114485
Summary: Widgets have transparent background
Product: LibreOffice
Version: 5.4.3.2 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: graphics stack

Screenshot of the problem
Widgets rendered by the VCL toolkit don't have alpha on the backing store set
properly. The screenshot explains it best.
We also have it in the grey area behind the white document in writer.
Problem exists in multiple window managers. Turning off WM compositing masks
the problem.
In libreoffice GL acceleration is off (and apitrace shows no calls)
VCL backend is GTK. Changing the VCL toolkit doesn't seem to make a difference.
It's fine on my main machine, this happens on a specific ARM64 laptop. Whereas
other apps (Qt4, Qt5, GTK2, GTK3) all work fine. I assume it's something quirky
with our X drivers that libreoffice isn't handling the same.
Happy to get any other information requested.
(reproducible with libreoffice 5.1 and 5.4)
