Originally created by @thalieht on GitHub (Mar 22, 2017).

qBittorrent version and Operating System:

Current master 3.4.0 alpha, Arch KDE

If on linux, libtorrent and Qt version:

Qt 5.7.1, libtorrent 1.1.1

What is the problem:

qbit crashes if add new torrent dialog is resized horizontally with the cursor on the edge of the screen the moment metadata is loaded (window position resets).

In KDE it's allowed to resize this window while it's out of focus (unlike win 7)

Steps to reproduce:

Load a magnet link
Before metadata is fetched click outside the add torrent window.
Resize window horizontally to the edge of screen and hold the resize.
When metadata is fetched qbit crashes (if window position is reset)

Extra info(if any):

I have also seen it crash during some other stuff in add torrent dialog such as when opening the "save at" history or "category" the moment the window is reset. I've even seen it crash the moment metadata is fetched without me doing anything at all but it seems random.

The inferior stopped because it received a signal from the operating system.

In latest 3.4.0alpha, and after many tries, i can no longer replicate because the addnewtorrent window's position doesn't seem to reset on metadata retrieval anymore and because it's no longer possible to resize that window without it being in focus (clicking on the edge of the window now puts it in focus).

I have no idea if it was some update in KDE or qbit or a combination that fixed it.

I get a similar crash if, before the metadata finishes downloading, I try to change the download folder. It seems to primarily when the dropdown / select window is active at the moment the metadata finishes, but it has done it to me before even after confirming a new folder. Should I make a new post or is it sufficient here?

We are closing all issues related to old qBittorrent versions (qBittorrent < 4.1.0).
Please, update to last release and, if the bug/error/crash is still present, open another issue.
Thank you.
