已知兼容问题

硬件方面

已知以下软件在启动时会使MuseScore崩溃：

• Samson USB麦克风，驱动名"Samson ASIO Driver"，samsonasiodriver.dll。查看详情
• Digidesign MME Refresh Service。查看详情
• Windows XP SP3 + Realtek Azalia Audio Driver。查看详情
• Wacom平板。查看详情及QTBUG-6127

软件方面

• Maple virtual cable is known to prevent MuseScore from closing properly.
• KDE (Linux) window settings can cause the whole window to move when dragging a note. Changing the window settings of the operating system avoids the problem.
• Nitro PDF Creator may prevent MuseScore 2 from starting on Windows 10, if being used as the default printer. Same for Amyumi/Quickbooks PDF Printer, see here and also some cloud printing services, see here.
• Creative Sound Blaster Z Series ASIO driver may prevent MuseScore 2 from starting on Windows 10.
• Untrusted Font Blocking policy prevents MuseScore 2 from starting (except in debug mode, i.e. using the -d option) on Windows 10. (Solution in the links provided here)
• The SteelSeries Engine 3 Audio Visualizer will prevent MuseScore from starting up, or cause MuseScore to crash if the Audio Visualizer is started when MuseScore is already running.

AVG Internet Security hangs MuseScore

MuseScore requires access to your internet connection with AVG. MuseScore doesn't need an internet connection to function, but if AVG blocks it, MuseScore hangs.

If AVG prompts you, Allow MuseScore and check "Save my answer as a permanent rule and do not ask me next time."

If it doesn't prompt you anymore,

1. 打开AVG用户界面（右键单击靠近系统时钟的AVG图标 -> 打开AVG用户界面）
2. 点击防火墙
3. 点击高级设置
4. 点击应用程序
5. 在列表中找到MSCORE.EXE并双击
6. 将Application Action改为 Allow for All

macOS上的字体问题

众所周知，当某些字体在macOS上损坏时，MuseScore会将音符显示为正方形。
要对这个问题进行故障诊断：

1.转到应用程序->字体书
2.选择一种字体，然后按⌘+A将其全部选择
3.转到文件->验证字体
4.如果报告任何字体损坏或存在小问题，请选择并删除它
5.如有必要，重新启动MuseScore

在此帖子中，用户认为发现字体“Adobe Jenson Pro（ajenson）”是罪魁祸首，无论根据上述验证没有被报告为损坏或有问题，并通过删除该字体解决了问题，因此这也值得检查。

Linux上的字体问题

If the default desktop environment application font is set to bold, MuseScore will not display the notes properly.
要对这个问题进行故障诊断（gnome 2.*/MATE用户）：

1.右键单击桌面并选择“更改桌面背景”
2.点击“字体”选项卡
3.为应用程序字体设置常规样式
4.如有必要，重新启动MuseScore

For GNOME 3/SHELL users

1. Open the shell and open "Advanced Settings"
2. Click on the Fonts option in the list
3. Set the default font to something non-bold
4. Restart MuseScore if necessary

Linux上“另存为”对话框为空

一些用户报告称，Debian 6.0和Lubuntu 10.10上的“另存为”对话框是空的。

要对这个问题进行故障诊断：

1. Type the following in a terminal

   which mscore

2. 该命令将以mscore的路径回答。使用您偏好的文本编辑器进行编辑，并在开头添加以下行：

   export QT_NO_GLIB=1

启动MuseScore，问题应该得到解决。
