Some shapes do not exist at the thumbnail

Some shapes do not exist at the thumbnail. Aspose.Slides for .NET 2.8.3.0
Example attached. (upper red shape is not rendered)

Dear x_ray,

Thanks for reporting, we will fix this bug as soon as possible and let you know.

How are things going with solving this problem?

Sorry for delay, we are focused on the pptx format and didn’t have time to fix it yet.
But we will try to fix it asap. Thank you for reminding.

The problem was fixed in 2.8.8 version.
Please download it here.

Attached ppt still looks with problems at thumbnail even with Aspose.Slides.2.8.9.0
(wrong text background)

If I’m not mistaken, solid background inherited from master slide.
We will investigate why it happens and fix as soon as possible.

Is there any update to this issue? We are experiencing this was well and we need to release very soon. A fix sooner then later would be greatly appreciated.
Thank You,
Eric

Hello,

Sorry but I’m afraid we can’t fix it in a short time. We can’t even find why it happens.
All properties of the shape tell that text has red solid background but PowerPoint shows it as transparent.
By my opinion there is something wrong with the PPT file.
