Got it, thanks for the screenshot. I’ve just tried to open the attached files and all worked except a9g89-uu69d.dib. The apng and ai files opened. We’ll take a look at the issue with dib and overlay.

It seems that the attached .dib file is corrupted. I have failed to open the file with desktop viewers such as IrfanView and Windows Photo View. Furthermore, the attached file does not have the required header see Bitmap file header

The header field used to identify the BMP and DIB file is 0x42 0x4D in hexadecimal, same as BM in ASCII.

and this screenshot where I’m comparing our test file with attached dib-headers.png (129.0 KB)

The attached AI file is actually PDF file. To render the file you can change a file extension to .pdf or please share which demo project your are using so we could provide a temporary workaround.
