Describe the issue

I'm on Linux Mint and everything seems to work fine, as long as the window stays where is was opened.
The window freezes as soon as you drag it.

How to reproduce (Optional)

1. Open GitButler GUI
2. Drag across screen
3. Now you can't do anything within the window

Expected behavior (Optional)

1. It should not freeze/crash

Relevant log output (Optional)

These are the logs i get (the ui logs are empty)

Thanks a lot for reporting.

Could you try the latest Nightly by any chance? Maybe that was just intermittent.

Thanks again.

And just in case, CC @slarse in case this is known already.

The nightly build does the same

This is not a known issue afaik. I also cannot reproduce it on any of my three machines (Arch, Ubuntu 22). I don't have a Mint setup, unfortunately.

As the issue occurs when moving the window, it's probably not an issue with the app itself (although it's not impossible). My guess would be on WebkitGTK.

@jbh-1994 if you start the app from a terminal, do you get any interesting error messages there? Do you see any CPU or memory usage spikes?

[jbh-1994]

It could be it's something with the OS.

There are no crash logs or anything, even when running through terminal.

My CPU hovers around 20% or so.

[jbh-1994]

Okay, something new.
1 of my CPU cores spikes to 100% and stays there for a while, until another one takes over and spikes. This happens from the moment i selected the repo.
So the issue does not exist before choosing the repo.

[jbh-1994]

I tried with a smaller repo and it works just fine with that one. So could the size of the repo have something to do with it?

Edit:
I cloned the big repo again, but through GitButler and now it seems like it is working.

[slarse]

So something must have locked up when dragging the window. I wonder if the dragging of it was causing rerenders. But then it worked when cloned anew so that doesn't seem entirely likely.
