css - Eclipse 4 用户界面慢。 CSS 引擎调用过于频繁 (Windows)

我有一个 eclipse 4 RPC 应用程序，它在 Windows 上运行速度非常慢。在 macOs 上，问题似乎不存在。当我将焦点从一个窗口更改到另一个窗口时，光标开始闪烁需要大约 3 秒的时间。该 View 有大约 500 个控件(文本字段、标签、按钮)，但其中大部分是隐藏的。

我不允许粘贴代码，但我在那里做了一些分析。我发现 eclipse 4 的 CSS 引擎在重新渲染时做了很多操作系统调用。这对我来说没有意义，因为我们根本不在元素中使用 CSS。

这些是发生超过 100 次的调用:

如您所见，OS.java:2828 org.eclipse.swt.internal.win32.OS.GetPropW(long, long) 之类的调用次数超过 230,000 次。

问题:

  1. 是否可以完全关闭 CSS 引擎？
  2. 有人知道我可能做错了什么吗？

最佳答案

问题已在 https://bugs.eclipse.org/bugs/show_bug.cgi?id=558227 中报告与建议的代码更改。

关于css - Eclipse 4 用户界面慢。 CSS 引擎调用过于频繁 (Windows)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58451881/
