Weird performance issues while dragging app's window

ricard-v commented 1 year ago

Hi there.

First of all, thank you for tackling on the issue of translucent windows in desktop apps.

As stated in the title, I get really poor and weird performance when dragging my window: it is very laggy and depending on the effect, it behaves erratically.

I have tested Windows only for now.

Using the following effects:

Transparent: no issue, perfectly smooth
Areo: quite laggy (definitely around 30 FPS, possily less)
Acrylic: somewhat not that laggy, but slow as hell and erratic. When I drag the window, it lags behind my mouse. There is an after-effect where the mouse is stuck in the app. When I release my mouse, it re-appears and a few seconds later the app's window arrives at final position.
Mica: cannot test (not using Windows 11).

Obviously I tried in profile & release mode but there is no effect. My computer is now slow:

i don't get the same behavior with other Windows apps
It sports a 7th Gen i7 Intel Core and a RTX 2070.

Does anyone get that issue ?

Same! With acrylic, moving the window just lags enormously, and the mouse cursor also lags behind, as you said. As for aero, I don't have this issue; it works just fine.

On version 1.1.0+1
