MrStonedOne, I'm getting an issue where the admin interfaces and stuff wont load, and will just be a white screen sometimes.
Retrying will usually fix it, but it's super annoying

Is one example, but i've gotten reports from users and other admins.
I'll need a lot more info on this: screenshots and the like.
Ok, further testing has shown that it only occurs the first time that it's opened, and the delay seems to occur for about 15 to 30 seconds. I'll try and get a screenshot of it.
It doesn't seem to occur every time either.
Ok it's gotten more common for me now.
Basically getting this every time I open an html window for the first time after the server boots. Sometimes it can even happen twice.
This doesn't seem to have anything to do with the time since world start either, as I've had it occur 30 minutes in.

Shadowlight, I suspect you may have antivirus and/or firewall software interfering here.
I tried modifying my av and firewall settings to exempt byond and dreamseeker. Not getting any change
Problem continues to intensify.
Sometimes it shows a little loading icon by my cursor, sometimes not.
Just earlier today, I had a window open fine, closed it and tried to reopen it and had the white screen appear.
Users on Goonstation have experienced this problem as well. However, in addition, it spawns lots of dreamseeker.exe processes forever that eat up memory on your computer and eventually crash unless you force-close the game dreamseeker process.
This keeps happening.

I finally got it to happen to me! Yay!

I can confirm that the file gets to the users cache but after being written no attempt to read it happens.

I can also confirm (via packet capture) that no attempts to actually request the page from ds occurs

Edit: ya, the window opens, but no navigation attempt happens. Moving your mouse around the window causes a loading icon to show and flicker, but it goes away the exact moment the mouse stops moving.
More data!

I used winspy++, started with the main browser window, and worked my way down the children. so window -> #somenumber -> shell embedding -> shell doc object

I did this on both.

The left window is a working one.

The right window is a non-working one.

As you can see, the inner IE webcontrol is never created in the right window.

That should hopefully narrow this down.

Edit: I just noticed, I'm still on 1383, I'll upgrade later, hopefully that doesn't matter. It doesn't look like anything related to this was changed.

edit2: after 5 to 10 minutes the browser control shows up with navigation cancelled

The only problem is, I can't replicate this. I don't know why the required control isn't being created.
Ya, i feel it, I was hoping that hint might trigger some ah ha! moment.

We know it has to do with the control not loading immediately.

We know that no attempt to connect to the DS webserver happens

We know that the window is created.

We know it has to do with the 1373 (i think) change to how DS loads the html windows to a webserver framework.

That SHOULD narrow it down pretty far.

Maybe go over the diff for that version and look for obvious fuckups. The randomness of the bug suggests it would likely be a uninitialized read or maybe an overflow/underflow/out of bounds issue.

Because the underlying code for the browser control didn't change all that much, I don't think that's it. I suspect there's some sort of bizarre timing issue in play.
