Freezing on Windows

Open enetkilifatih opened this issue 3 years ago • 3 comments

Expected Behavior

Fast UI running on Windows like as fast on Linux.

Current Behavior

It's freezing sometimes, for example at the following operations;

  • When launching application, the UI sometimes appears 1-2 minutes later after double-click, and never happened on Linux.
  • When we click Application Settings, sometimes it's freezing for a while about 1 minutes.
  • When we click Firmware settings under Vehicle Setup, it's freezing for a while about 20 seconds.

Steps to Reproduce:

  1. Have a network connection without internet.
  2. Try above operations.

System Information

  • Operating System: Windows 10
  • QGC Version: 4.1.6, 4.2
  • QGC build: stable
  • Flight Controller: [e.g., Pixhawk I, Pixhawk Mini, Pixhawk 2, etc.]
  • Autopilot (with version): [e.g., PX4 1.8.1, Ardupilot Copter 3.6.1]

Detailed Description

I have faced these freezing issues more at unstable network connection. For example, set your ip statically to wrong subnet (you won't have internet connection). Your machine will be connected to a network but no internet. In this stuation, freezes are increasing. However these freezes never happened on Linux under same circumstances.

It seems that the problem is a bug in FileDialog of Qt. And I realized that the delta of my env and the others is to have some network drives. If explorer.exe freezes when opening a network drive without connecting the necessary network, then any Qt App which contain FileDialog freezes in the same way.
