--- Comment #3 from Luboš Luňák <l.lunak at collabora.com> ---
- This only shows with OpenGL disabled either on Windows, or on Linux with the
"gen" vcl plugin (SAL_DISABLEGL=1 SAL_USE_VCLPLUGIN=gen). So this shouldn't be
a dependency of the VCL-OpenGL bugreport. Given that we default to OpenGL on
Windows and on Linux pretty much nobody uses the gen plugin, most users
shouldn't be affected.

- It is related to bug #80498. Presumably reverting that fixes this but
reintroduces that problem. Making the image lose the alpha channel should also
avoid the problem.
