UI is freezing of an mingw 64 compiled Application while download is active

[AlexanderTonn]

I have the current problem that my application is getting stuck if i do an download with the sftptablemodel test code. I also rewrote the "secure uploader" example to download a file (basically i think that i understood the mechanics of QSsh), but the phenomenon is the same. I try to download files with the size of about 50Mbs. The download works, but the UI is freezing (the CPU load is only at about 20%) and the download in the background is very slow. So i need aber 10-20 Minuts with an 25Mbit internet connection. In addition to that the QT IDE is crashing while i'm debugging the application

The Server which i'm connecting to is an linux based sftp Server from an webspace provider (IONOS). The download works properly with FileZilla

My Question:

• is there probably an X11 Forwarding which i have to disable?
• any other suggestions?

I use the following branch:
