x11中的重叠窗口不断闪烁 [英] Overlay Window in x11 keeps Flickering

问题描述

我采用了此答案中的代码，以便绘制覆盖窗口，它始终位于所有窗口的顶部.但是我发现，每当按键或单击按钮时，此窗口就会一直闪烁.我想知道这是否可以通过某种方式停止.增加时间对我无济于事，因为当我增加时间到5000000000

I adopted the code from this answer in order to draw an overlay window, which stays on top of all windows, always. But I find that this window keeps flickering whenever there is a keypress or a button click. I wanted to know if this can be stopped somehow. Increasing the time did not help me, as my terminal was frozen for few seconds when I increased time to 5000000000

该代码已在 Ubuntu 16.04 LTS 上进行了测试.

推荐答案

我找不到使用XComposite函数集的解决方案.但是，您可以通过CWOverrideRedirect以更大的灵活性和纯X11轻松获得相同的效果.您可以在此处查看示例用法: https://stackoverflow.com/a/57780772/4204557

I could not find a solution using the XComposite suite of functions. However, you can easily achieve the same effect with (in my opinion) much more flexibility and pure X11 via CWOverrideRedirect. You can see example usage for it here: https://stackoverflow.com/a/57780772/4204557
