2 years ago After further investigation it seems that the issue always affects the small square tiles in the "2" directory:
- 2/b1_1.jpg
- 2/d1_1.jpg
- 2/f1_1.jpg
- 2/l1_1.jpg
- 2/r1_1.jpg
In the following example, I have filled those tiles with a bright red color.

With the replaced tiles, a red flicker is sometimes visible at the respective positions when the panorama is carefully scrolled. I believe that along with the web server log file, this shows that they are requested from the server but some sort of display issue happens.
The original tiles look nice and sharp:

Hello!
First of all, thanks a lot for your work on Pannellum, which always performs wonderfully everywhere I take it.
Right now I'm dealing with a small issue that looks like one of those internet rendering flaws to the causual viewer, but I've discovered a bit of a system behind it. The issue is, that somewhere between moving multires generation from a hosted VPS to a local server at my home and a few Debian upgrades (oh, and also increasing panorama resolution a LOT), my setup has started to give me a set of blurred tiles (when fully zoomed out) in a square around the nadir of the photo. Three of them square, one L-shaped.
Examples:
Imagine a radius of about 1-2 meters around the nadir and they should be easy to spot. In the attached crop from the second example, one patch is under the bench and one is visible on the right.
The respective configurations:
Raw panoramas:
The blurred tiles are visible browser- and client-independently, so I imagine the blur must be happening either in generate.py, in Python's PIL or somewhere in the interaction between the viewer and the multires directories.
Invocation of generate.py:
generate.py -q 95 -o "${pano_dir}" "${file}"If I can provide any other details or test things, please let me know.
