...flare at 70mm f11 in direct, low sunlight:

FWIW, that's almost certainly the purple grid flare common to X-Trans cameras and has nothing to do with the Tamron. Fuji had stated it was fixed with the X-T3. But I shoot a lot of landscapes as well and you can still find it when the sun is in the frame, the aperture is small-ish and light hits just right.
Here's one starting to manifest with the XF 70-300mm (lens is only at f/7.1 or it would be stronger):

It's actually a flare pattern common across most brands of mirrorless cameras. Google "red dot flare" and you'll see numerous discussions and opinions about it. It happened with my Nikon Z5 and Panasonic S5 too. I took a series of photos from f2.8  to f16 with the 17-70 purposefully to show the flare pattern in these conditions. The good news is it can be avoided and doesn't always display.

In these pics you can see it's almost the same conditions, but the flare pattern is being avoided:
