As the title says, this is no longer working correctly.
14.8.12.12 - SetTransparencyPercent  to 75

15.12.21.12 - identical code

Can someone respond about this introduced bug please?

Hi Kevin,
This problem is most likely caused by the fact that we updated the surface rendering for performance reasons as well and some OpenGL state is not as it used to be (in fact it would be anyway incorrect to regard the alpha setting of the fill when the surface uses zoning). We'll be looking to resolve this in the upcoming major release of the control when we plan to have better alpha support in general.

When is this release likely to be please? I have not been able to update Vision since version 14.8.12.12 because of various changes in behaviour and regressions in chart and mapping functionality. That's over 16 months.

Hi Kevin,

The next major release is expected in March - early April this year.
