Very slow document opening

[MikeTO]

Some documents are very slow to open in 2.6. For example, my Publisher manual takes 25 seconds to open in 2.6 but just 2 seconds in 2.5. It stalls at the mid-point of loading for a while and then the progress meter disappears and the document window is opened.

I believe the stall is happening before it gets to loading any external resources because if I hide them, the progress meter disappears after the same amount of time and then does its normal stall while failing to find resources before opening the document window.

It will happen even when opening from an un-synced part of my internal SSD and it doesn't matter if the file was saved from 2.5 or 2.6. It doesn't happen with all complex documents - my history book loads just as quickly as it did in 2.5.

If you can't reproduce it, please let me know and I'll send you a package.

I saw the same, when I did some tests regarding the slow font selection issue.

Does the open delay correlate to the number of OpenType fonts/styles used? For me, it does: I just created two test documents, one that contains three paragraphs, using three TrueType fonts (loads quickly), one with three paragraphs, using three OpenType fonts (takes long).

@Daniel Höpfl You figured it out, thanks!

This file opens instantly in 2.5. After restarting Publisher, it takes 15 seconds to open in 2.6. If I close the document and re-open it then it opens instantly. The document uses only multiple variations of Roboto Flex.
