Does this happen in all cases or only for specific binaries / structures / after a specific time / after performing specific actions? I can't reproduce this when simply opening a file and browsing around.

Im using BN with large binary (around 60MB), so my DB is around 2GB after saving, i can send binary here if you want

Also, structure window is hidden by default to the right side here

If you could upload the binary that triggers the bug that would be appreciated. I spent some time poking around ntoskrnl which is admittedly only 8MB, and didn't see anything like what you described.

In the second picture it looks like the splitter widget has shrunk. You should be able to expand it by dragging on the ... dots (there are two, you want the left one).

I also have added PDB file: https://file.io/aIz367GMNklA

Also, sometimes it's stops displaying xrefs on structure fields

Also, Binary Ninja does not close after closing the window, although it has been at least 2 minutes

Thanks for the test case. Vector 35 employees can search for silenced tapioca serpent puppet to find it and the provided PDB.

I tried loading the binary you provided and still couldn't reproduce this. Does it still happen if you start with plugins disabled / cleared settings?

We have been unable to reproduce this, so I'm going to close it. If we've missed a step or if there's more information/test cases you can give, please let us know and we can reopen it.

I suspect that at least one of the issues described here is a performance problem, but it's difficult for us to troubleshoot it in this specific instance without more information about hardware and settings.

Reopening this because I found a way to reproduce it which I think is accurate to the issue:

1. Add binary to project
2. Open binary
3. Open types view
4. Save binary
5. Now types view is broken

It looks to be the action of saving the binary that is causing this.

Fix for this is going out in >= 4.1.5432-dev
