Why prototyping feature does not work well?

When I play my prototype, the presentation of the frames looks bad.
This error happens also playing the prototype of Figma`s tutorial examples!
Please, find attach the screenshots

.
Can you help me?

I too am facing the same problem

This is a known bug, I don’t think there is a solution but try updating your GPU drivers. Also report it to Figma support team via the bug report form.

Thank you

Thank you, I will report it. I selected the same dimensions of the device to run the prototype as the designed frame, but it did not fit it well.
