+1. Bugs #30539 and #32159, for instance.

I don't see this problem in my usual setup on Windows, probably because
I have configured the fonts used in `fontset-default', resulting in
shorter searches for suitable fonts.
As Eli pointed out in a previous discussion, configuring the default
fontset to contain the right fonts for multiple versions of Windows is a
fair amount of work, and would require ongoing maintenance.
Given that, setting inhibit-compacting-font-caches non-nil on Windows
seems a pragmatic workaround.

I think we should make this variable non-nil by default on
MS-Windows.
There are quite a few bug reports in the bug DB which all complain
about slow redisplay on MS-Windows, and were resolved by setting this
variable non-nil. So it sounds like on MS-Windows the compacting of
the font caches is not a good idea (the original code was written to
fix a problem observed on X).
Any objections/comments?

No objections, so I've now made such a change on master.

Since there have been no objections, perhaps it's time to do this change?
Best regards,
