Description
Thread:: https://forum.playcanvas.com/t/change-image-ui-sprite-in-runtime/19700/5
Project: https://playcanvas.com/editor/scene/1138025
On desktop:
On Android chrome:
It renders correctly if it's a sprite component but not as a UI element.
My guess is that the texture height >4K so gets downsampled by the engine and has affected the UI rendering in some way.
Making the texture 50% smaller worksaround the issue.
