Additional context

Note: Windows will occasionally open in a 1px by 1px window which is a known bug with hyprland/steam windows when assigned to a workspace but can be resized to the correct size

you can assign for rules for size instead

"Note: Windows will occasionally open in a 1px by 1px window which is a known bug with https://github.com/hyprwm/Hyprland/issues/4976 but can be resized to the correct size"

example as below
windowrulev2 = size 70% 70%, class:^(xdg-desktop-portal-gtk)$

[darkeddie]

With:
windowrulev2 = size [x] [y] or windowrulev2 = minsize [x] [y] - I find that it tends to freeze/crash steam or bug out the window and quite often just ignores it.
So not having it and opening small 1 out of 20 opens was better than 1/3 opens hanging or crashing.
