The ornamental design for a displayscreen or portion thereof with transitional graphical user interface, as shown and described.
The file of this patent contains at least one drawing/photograph executed in color. Copies of this patent with color drawing(s)/photograph(s) will be provided by the Office upon request and payment of the necessary fee.
FIG. 1 is a first image in a sequence for a display screen or portion thereof with transitional graphical user interface, showing my new design;
FIG. 2 is a second image in a sequence thereof;
FIG. 3 is a third image in a sequence thereof;
FIG. 4 is a fourth image in a sequence thereof; and,
FIG. 5 is a fifth image in a sequence thereof.
The perimeters of the portion of the underlying display screen and the graphical user interface are understood to be flush.
The appearance of the transitional image sequentially transitions between the images shown in FIGS. 1-5. The process or period in which one image transitions to another forms no part of the claimed design.
