HiDPI screen has blurry cursor/pointer rendered with 200% scaling

This is how the cursor looks like in wayland:

This is how the cursor looks like in xwayland window:

I tried to use Xwayland -hidpi and xprop -root -f _XWAYLAND_GLOBAL_OUTPUT_SCALE 32c -set _XWAYLAND_GLOBAL_OUTPUT_SCALE 2 to reproduce this issue from just Xwayland, it has the same result. So this might not be an issue caused by xwayland-satellite. But I wonder how can I get rid of this? Before I switch to niri I used gnome, which works perfectly with xwayland in 200% scaling.

BTW I have some Qt apps can not scale 200% properly (only font can be scaled correctly, icons are pixelated).

I tried with niri rootful mode Xwayland :0 -hidpi -dpi 244 (244 is my screen's dpi) and

GDK_SCALE=2 \
            GDK_DPI_SCALE=0.5 \
            QT_SCALE_FACTOR=1 \
            XCURSOR_SIZE=24 \
            DISPLAY=:0 wps

to run the xwayland app. Even though the cursor is still blurry, the app by itself looks better (All icons are rendered not pixelated as xwayland-satellite does).

And I also tried gnome rootless mode Xwayland :0 -rootless -hidpi -dpi 244, which works perfectly with cursor not blurry and contents are perfectly rendered without pixelated icons.

This is probably a bug, so I opened a bug for it: #194
