I'm on MacOS Ventura (Arm) and the newest version of Yabai. Most other apps split correctly. For example, when I drag a tab from Firefox to create a new window, the two Firefox windows split in half. However, on Chromium (and regular Google Chrome), the two windows don't split in half at all. One window gets larger and engulfs part of the other window. Here is my config file:
#!/usr/bin/env sh yabai -m signal --add event=dock_did_restart action=sudo yabai --load-sa sudo yabai --load-sa
yabai -m rule --add app="Code" opacity=0.8 yabai -m rule --add app="kitty" opacity=0.75 yabai -m rule --add app="Obsidian" opacity=0.75
