Inconsistent selection behavior when dragging to select items

I'm experiencing an issue with the selection tool in Figma. When I try to click and drag to select multiple items on the canvas, it often fails to work properly. Sometimes it only selects some of the items within the selection box, and other times it doesn't select anything at all even though I'm definitely dragging over layers. And then I have to select them one by one, the only way it works.
