描述

Description

When opening other windows such as settings one and then closing it, there is some "replacement effect" where there's a visual effect showing the taskbar icon being replaced by something else. Sometimes, what comes to replace… have no icon at all.

Steps to reproduce

Repro rate is not 100%.

  1. Open settings
  2. Change for example language
  3. Close settings
  4. There's this taskbar icon replacement effect, and sometimes it replaces with something with no icon.

Reopening and closing settings after this reinstate the icon. But we can trigger the bug again after that.

This is a screenshot of… Mumble in the taskbar when the bug istriggered. Unfortunately I found no way of having the preview when hovering while taking the screenshot. Capture

研究方向
Investigate the Windows task bar icon management in Mumble's client code. Focus on how the application icon is set and updated when the settings window is opened and closed. Look for code that handles window visibility changes or icon replacement. The bug may be related to incorrect handling of icon resources or window messaging. Review the Qt or Windows API calls related to task bar icons.
