           Summary: major regression in dnSpy startup time
           Product: Wine

          Hardware: x86-64

(OK, this will be quite a bit different than what I've planned when I started
to write this)

Let's start with an oddity: only 32bit versions of dnSpy work, 64bit fail to
show anything besides the recently popular stack corruption line (it does not
terminate upon it, but fails to do anything else either).

The problem (initially observed in 6.1.8, but dnSpyEx 6.3.0 has the same
problem):

I'm not quite sure when this happened, but IIRC it was at most two releases
back, maybe it was the latest one.

Before, upon startup there was a minor delay before the window showed up and
every now and then (but relatively rarely) the window got filled with visual
garbage until it was refreshed.

Now, it *seems* corruption has been dealt with (though that needs more time to
be verified), but there's a crippling startup delay (over 2-3 min) between when
a blank window shows up and when it's filled with content.
