How can I set a position/size of directframe, lets suppose I want a frame that cover 1/4 of the width of the screen and all height, don’t matter the size of the screen and he keep with this relation doesn’t matter how much I resize the window, is it possible or should I return to opengl or migrate to vulkan?
Hi! I don’t think that it is supported ootb, anyway you have all you need for adding this straightly. You can listen for the event window-event, and resize the frame in the callback.
Actually it is supported 
You can reparent your direct frame to either aspect2d or render2d, depending if you want to keep your aspect ratio or not, see https://docs.panda3d.org/1.10/python/programming/scene-graph/scene-graph-manipulations
A frame covering all height and only the left 1/4 of the screen would have (-1, 0, 1) as upper left corner and (-0.75, 0, -1) as lower right corner.
