Description
VNote requires openGL and it may not work well on Windows by default.
Strange behaviors include:
- Interface freezes and does not response (especially in read mode);
- Widgets are out of order after maximizing and restoring the main window;
- No cursor in edit mode;
- Menus are not clickable in full screen mode.
There are several ways to solve this issue:
- Try to assign an integrated display card to VNote if available;
- Try to update the driver of display card;
- Specify openGL option to use by doing either of these:
- Declare a system environment variable named
QT_OPENGLand set its value to one ofdesktop, orangle, orsoftware; - In
Settingsdialog of VNote, select one of the openGL option and apply.
- Declare a system environment variable named
Restart of VNote is needed and it is recommended to close all the notes before trying to specify openGL option.
VNote依赖于openGL,而后者在Windows上默认可能无法正常工作。
一些奇怪的行为包括:
- 界面冻结,无响应(特别是阅读模式);
- 在最大化并还原主窗口后,窗口部件错位显示;
- 在编辑模式无法看到光标;
- 在全屏下,菜单无法点击。
可以尝试以下几个解决办法:
- 如果是双显卡,可以尝试将VNote调度到集成显卡上;
- 可以尝试更新显卡驱动;
- 通过以下任意途径指定openGL选项(可能需要尝试多次以找到正确的选项):
- 声明一个名为
QT_OPENGL的环境变量,其值为desktop, 或angle,或software; - 在VNote的设置对话框里面,指定一个openGL的值,重启VNote看是否有效;
- 声明一个名为
以上操作需要重启VNote以生效,而且建议在尝试openGL选项之前关闭所有笔记。
