Display screen or portion thereof with transitional graphical user interface

Abstract

Description

FIG. 1 is the first image in a sequence for a display screen or portion thereof with transitional graphical user interface showing my new design;

FIG. 2 is the second image thereof;

FIG. 3 is the third image thereof;

FIG. 4 is the fourth image thereof; and,

FIG. 5 is the fifth image thereof.

The outermost broken line in the figures depicts a display screen or portion thereof that forms no part of the claimed design. The remaining broken lines in the figures depict portions of the transitional graphical user interface that form no part of the claimed design.

The appearance of the transitional graphical user interface sequentially transitions between the images shown in FIGS. 1 through 5. The process or period in which one image transitions to another forms no part of the claimed design.

Claims

I claim the ornamental design for a display screen or portion thereof with transitional graphical user interface, as shown and described.
