X11 window size and cursor size inconsist with the scaling of gnome

[YaQia]

Describe the bug The first kitty opened in gnome will have this problem when having 200% scaling. Once your initial_window_width and initial_window_height are set with col / row numbers, the window will shrink to 1/2 width and 1/2 height. Additionally, whatever initial_window_width and initial_window_height are, the cursor size of it will shrink to 1/2 width and 1/2 height.

To Reproduce Steps to reproduce the behavior:

1. Login to gnome (to ensure you haven't open any kitty window)
2. Open a kitty terminal with X11 as linux_display_server. More specifically, full config is:

3. Move your cursor up to the window
4. You will notice the cursor size is shrunk.

It is notable that this will only happen to the very first kitty terminal opened. That's why the video shows only one window with shrunk cursor.

[YaQia]

Now I guess it was gnome47 intruducing this bug, I have downgraded into kitty 0.33.1-2, still see the shrunk cursor.

On X11 your WM needs to se Xft.dpi for scaling to work properly. Report the issue to the WM developers.

[YaQia]

Nope, I am not using X11, just using Xwayland to run kitty. Kitty is the only application has this issue.

[kovidgoyal]

If you are using xwayland then you are running kitty with x11 so you need to set the appropriate settings in xrdb. Or run kitty using wayland.
