Hi @Lana_Diab,
Thank you for providing the screenshot. To gain a better understanding, could you inform me about the version of InDesign and the operating system you are using, whether it's macOS or Windows? It would also be helpful to determine if this issue occurs in a specific file or if it is present in all new documents.
Please attempt to toggle your display preview between GPU and CPU to check if the shape fills correctly afterward. This can be done from the View menu. If the GPU preview option is not present, there may be a compatibility issue. You can find more information here: https://adobe.ly/4iwxd3a
When you have some time, please share a brief screen recording that demonstrates your workflow up to the point where the problem arises, so I can attempt to replicate it on my end. If possible, providing one of the affected sample files would be extremely beneficial. If the content is sensitive, feel free to send it via DM using a public cloud link such as Google Drive or Dropbox.
I look forward to your response. I'm here to assist!
