IgnoreSizeHints - bakkeby/dusk GitHub Wiki
If a client has the IgnoreSizeHints
flag set then the all size hints of the window are ignored
regardless of whether it is floating or tiled.
The use case for the flag is as a workaround if the minimum size, maximum size, or fixed aspect ratio reported by the window is undesirable.
