Proxmox interface has become difficult to read

I am very much new to Proxmox and really enjoying the experience at the moment. One thing that is bugging me . . . .
I set up a Proxmox server in January and everything went well on a GMK mini PC. I have been playing with Home assistant and had no issues from Proxmox until about 2 - 3 weeks ago when suddenly the text on the web interface became harder to read. I can just get by using it but it is far from ideal. I have a windows 11 PC totally up to date with updates. During the time between when it was clean and crisp up to when the text became difficult to see I have not installed or deleted any fonts, I have not added or removed any software, but I can't say anything for Windows Update. It is possible they have taken place.

That said another Windows 11 Laptop I have see's it just fine and that is also up to date. The console is clear to read.

I have seen comments about Helvetica font's installed on the computer possibly being an issue. I temporarily removed them and cleared all the cache and it still persists.
Changing the font's in Chrome browser does not do anything to improve the matter so I am a little confused as to why my main computer is struggling to show the font correctly and the little used laptop is fine.

Does anyone have any suggestions what might be the problem!

Welcome, @mR JoLLy !
I would start with the usual suspects ;-)
- the "private mode",
- disabling add-ons,
- zooming-in or zooming-out,
- other browser.
 
Hi there Onslow. thank you for the Welcome. Yes I have done Private mode, I have not done any add-ons, Zooming in shows a very thin font that can be seen bit it's then a panning experience - not good.
It works fine from 3 other machines on the network all using Chrome. I would like however for the main machine to be able to work as it originally did.

I did a fresh install from an image downloaded 4 days ago. As a new install it has the same issue!

So annoying! Can anyone tell me what font's Proxmox tries to use for the menu's that might be a good start?
 
Looks like "helvetica, arial, verdana, sans-serif." That's Firefox right? right click and Inspect, then you can click this:

...and hover over anything on the page. Then on the lower right view the Computed values and search for "font":

It's the Chrome browser I have, but I took a look in the "info" button which is similar in function to the function on Firefox. Indeed I find the helvetica, arial, sans-serif there as you described. My PC has many fonts installed (I do graphic design) so I compared them to the other computers that I know can see the page OK.

Turns out the other computers don't have Helvetica. I have about 20 sub fonts for Helvetica so I have backed them up and deleted the lot from my PC. After a restart and clearing page cache it's back to normal. YAY!

I have a Helvetica Neu on my computer still so I might move instances of any deleted Helvetica types into the new format or something else. Helvetica is a less popular font these days but equally an important element of graphic design still.
