HDI Scale not scaling after minimised

Windows 11

Gigabyte Aero Laptop i7-8750h, 16gb Ram, gtx1070 (with updated drivers): Screen set to 3480 x 2160.

When I start tiled all the UI text is scaled as expected. However, when I have minimised it, particularly for a period of time (to do other stuff such as coding), once maximised again all of the UI text is tiny (unreadable by this old man).
