Mouse pointers moves jumpy when hovered over skiko window

[SergeevPavel]

Reproducible on: Fleet and JetBrains Toolbox 1.25.12569
Platform: Windows 11
Display refresh rate: 120Hz
Not reproducible on: IntelliJ IDEA Ultimate

So it looks like a problem with Skiko or maybe JBR17
But I have no idea how some user space code can affect os mouse pointer

You mean laggy? :)

The issue is probably related to G-Sync. I don't know many details, but as far as I remember, it happens, if the user forcefully enables GSync in desktop mode in display settings (but I am not sure).

We tried to fix this issue, but unsuccessfully so far. It is a bug/feature of NVIDIA drivers. Even Microsoft Terminal had this issue (or still has). We found a very hacky way to fix that - show 1px Swing Component above SkiaLayer. It seems when we use OpenGL (and Swing uses it if I am not mistaken), the screen switches to the continuous mode, not adaptive. But we haven't merged it, because we hadn't found a way to make the pixel transparent :D.

The issue in Compose

@igordmn I'm seeing this problem in Fleet and Toolbox even when G-SYNC is only enabled for full screen mode:

I have to disable G-SYNC completely to get rid of the stutter/lagging.
