Snippet to show the problem

With reference to Bug 575425.

Run the attached snippet on Linux. The cursor has a black background when the *.gif source and mask images are used.

Now change the snippet so that the *.png image files are used. The cursor is rendered correctly.

(Works as expected on Mac and Windows.)
Comment 1 Phil Beauvoir CLA 2021-08-17 07:06:28 EDT 
For information, the black creation tool cursors can be seen on Linux GTK in the following tools/frameworks:

- Eclipse BPMN Editor
- Eclipse Ecore Diagram Editor
- GMF Tool Palettes
- Sirius Tool Palettes
- Modelio Modeling Tool

In fact, any tool that uses Eclipse GEF 3.1 Palette creation tools.

In Archi, I have worked around it by creating my own Cursors using a single PNG image with transparency.
