Description Markus Keller

I20110512-2000, already happens in 3.6

This is the GTK version of bug 310387.

On Cocoa and on Windows 7, only certain images cause a problem with transparent pixels. But as the testbed in bug 310387 comment 9 and the screenshot in the next comment show, GTK has a problem with all images that have been loaded using the Image(Device device, String filename) constructor and then copied using SnippetBug310387#createCenteredTableItem(String).

With bug 345180, we released a workaround to HEAD of AnnotationsConfigurationBlock, so the original problem is not prominent any more on the preferences page (just the 'Override Indicators' annotation image has a small white rectangle).

Still reproducible on GTK3.22, 4.9 RC2, and Fedora 28.
