Windows resizing on focus change

[shot-codes]

When changing focus, the windows are resizing ever so slightly. This causes layout shifts that are especially apparent in terminal windows. In the screen recording below, note the window size in kitty flashing while focus is changing, as well as the layout shift taking place on the text in each terminal window.

I can't reproduce this. Please confirm it does not happen on base hyprland, then give more details about your setup such as hyprland.conf, monitor size, dpi and anything else relevant

I'm not entirely sure what you mean by base hyprland, If I could ask you to clarify I would be more than happy to try. I am on latest hy3-git(r209.65a849b-3) and hyprland-git (0.33.1.r20.efdf07e2-1). It's occurring on both my laptop and external monitors (eDP-1: 2560x1600, DP-1: 2560x1440). hyprland.conf below, it is running on integrated graphics, not nvidia.

By base hyprland I mean hyprland with no plugins.

[shot-codes]

Ah okay, the only plugin I am using is hy3 :)

[outfoxxed]

If it dosen't happen on base hyprland also check if #52 fixes it.

[shot-codes]

It's happening with border_part_of_window set to 1 and 0. I should note, this is occurring dependent on the amount of columns I have. Doesn't happen with 1, 2, or 4 columns, but seemingly with every other number of columns (tested up to 11

*edit
Just updated hyprland-git and hy3, behavior is still present

hy3-git r232.a562617-1
hyprland-git 0.33.1.r23.167f2ed3-1

[outfoxxed]

I've been able to reproduce this on my machine now but only unintentionally. Not sure what causes it yet.
