Mouse dragging lag and solution

[EYHN]

Problem

In Windows 10 higher than version 1809, after enabling this extension, dragging the window with the mouse will cause a very serious lag.

After my research found, it seems to be a problem inside DWM, the mouse polling rate is higher than the screen rate, causing the rendering request to block in the queue, and it looks like a mouse delay.

current solution

Learning from Seo-Rii's solution in his project, I've implemented a window move/resize throttle, it can skip some move/resize events to match the screen refresh rate.

This solution was added to this extension from v1.0.10. In my test, it performs well on the 144hz high refresh rate display, and there is no mouse lag problem. On a 60hz display, there is still a little lag, but it is acceptable.

This is not a perfect solution at now, we can discuss it here.

For what its worth, seo-rii/electron-acrylic-window#26 (comment) suggests enabling Vibrancy's useCustomWindowRefreshMethod toggle to avoid movement/resize lag.

I am very confused please can you tell me how to solve the problem step by step?

First of all, thank you for answering. But unfortunately, even though I tried this before, there is no change. And yes, I just tried again. And also I deleted all custom settings in my settings file but similarly didn't affect me.
Not: As a solution to the problem, I ran the Blur Test.exe file on the page they directed above and it was working fine.

@drementer, I haven't looked into it much but useCustomWindowRefreshMethod is part of a electron-acrylic-window wrapper around Electron's vibrancy (which this extension uses directly). You'd have to modify this extension to use the wrapper, and then modify the setVibrancy() call as per https://github.com/Seo-Rii/electron-acrylic-window#options for Windows clients.
