== Transparent PNGs appear broken on wikipedia ==
{{tracked|T419927}}
Not sure what happened exactly, but all transparent PNG images on wikipedia are now showing up blurry. You can see this particularly with [[Kratos (God of War)]], where both the infobox and lower image are blurry, despite previously being perfectly fine.

:Seems to be effecting "png" formats as well beyond transparent ones. [[:File:BGC_OVA.png|BGC OVA.png]] for example is blurry even on its preview page. It is also happening with some jpegs. Like this file (heads up, this file has some uhh imagery that is "unfortunate" to put it lightly.) [https://en.wikipedia.org/wiki/File:Sanma-no-Meitantei-game-cover-art.jpg here] which is a jpeg which is also compressed on its own article and the preview page, but on clicking on it, it retains its quality.

::This affects, from what I've seen, every jpg file whose width is less than 250 px. [[User talk:Nyxaros|<small><span style="color:OrangeRed; text-shadow:gray 0.2em 0.2em 0.4em;">ภץאคгöร</span></small>]] 23:24, 13 March 2026 (UTC)
:::Ah. Perhaps it's due to the recent change to allow only certain image widths to be served, instead of anything-you-like.

===Blurry thumbnails on sports uniform / kit template images===

Hello,

I noticed that many uniform template images used in sports infoboxes (such as Template:Baseball uniform and Template:Basketball kit) recently started appearing blurry on article pages, even though the original files on Commons have not changed.

This affects files uploaded by multiple users, not just my own, and the issue seems to only occur in the thumbnails. When clicking the file and viewing it on Commons, the image appears sharp.

Examples where this occurs:

Files I uploaded:

[[United States national baseball team]]

[[Puerto Rico national baseball team]]

[[United States men's national basketball team]]

Files uploaded by other users:

[[Cuba national baseball team]]

[[Japan national baseball team]]

There are many more examples all related to this kit templates, and possibly to other types of images and templates in lower resolution.

The ones I noticed though are images are used in Template:Baseball uniform, Template:Basketball kit, and similar templates.

Since the originals are unchanged and only the thumbnails look blurry, this may be related to thumbnail rendering or a recent MediaWiki change.

Is this a known issue, and is there a way to restore the previous thumbnail quality? [[User:ANTbook365|ANTbook365]] ([[User talk:ANTbook365|talk]]) 13:34, 13 March 2026 (UTC)

=== Doubt ===

Why do the images look very blurry when viewed in [https://i.ibb.co/WN28rkdF/Screenshot.png an article] and as a [https://i.ibb.co/Dgz3sjyv/Screenshot-5.png file page], but they actually look HQ when the file is viewed like this [https://i.ibb.co/jk4C6PSd/Screenshot-4.png] [https://i.ibb.co/gb1rdKwW/Screenshot-6.png]? Is this a new optimisation to improve performance or to tackle copyright restrictions? What is the reason behind images turning [https://en.wikipedia.org/wiki/File:Thiruda_Thiruda.jpg this blurry]?

:{{ping|Manick22}} It's a recent bug. See [[#Transparent PNGs appear broken on wikipedia]]. [[User:PrimeHunter|PrimeHunter]] ([[User talk:PrimeHunter|talk]]) 12:39, 14 March 2026 (UTC)
::When will this be fixed? [https://en.wikipedia.org/wiki/File:Inglourious_Basterds_poster.jpg This one] looks very blurry! [[User:Manick22|Manick22]] ([[User talk:Manick22|talk]]) 12:46, 14 March 2026 (UTC)

:{{ping|TheDJ|PrimeHunter}} It seems that not only png, the others file include jpg, jpeg, webp also have the same problem (the images look very blurry) and not only happen in english wikipedia, the chinese wikipedia have the same problems.

Appears to now be fixed, though you may need to purge the page to force the image to get unstuck. --'''[[User:PresN|<span style="color:green">Pres</span>]][[User talk:PresN|<span style="color:blue">N</span>]]''' 21:11, 16 March 2026 (UTC)
