Unsolved How to clear Vivaldi's Font Cache?

[codemann8]

I'm noticing that any site that uses the Roboto font, it is replacing it with an entirely different font instead for some reason (Dummies font to be exact, and looks awful). I searched for a solution to this and came across this reddit post: https://www.reddit.com/r/vivaldibrowser/comments/4tf6cn/font_rendering_looks_seriously_wrong_any_settings/

One of the suggestions was to delete the Chrome Font Cache as it has been known to get corrupted sometimes, however, I don't know how to do this. I'm also on Win7 if that changes the method needed to delete it.

@codemann8 Hi, check your Settings > Webpages > Fonts.

Defaults are:

There is no option for clearing "font cache" and the file referenced in the (very old) Reddit article does not exist.

Try also clearing cache.

If you don't want to clear all cache but only for the site:

• Click Site Info button (lock icon), Site Settings, Clear Data.
  or
• Devtools (F12), Application tab, Storage, Clear site data.

None of the above resolved the issue. I should be clear that ALL sites that reference Roboto font has this issue, so it's not a specific site.

Also, if I open the same page in Chrome directly, the same weird font shows up there too.

But thru Dev Tools, if I edit the CSS to remove Roboto, the font changes back to something more reasonable.

I don't have a special Roboto font installed so I'm not sure where it is actually sourcing this font from.

@codemann8 You read a more than 5 yr old reddit.
There is no Chromium Font cache you can reset.

Font display problems are mostly caused by:

• one broken installed Windows font
• broken Windows font substitution
• broken graphics driver
• Graphics card's panel settings optimisation f.ex. FXAA or similar anti-aliasing
• a active Hardware Acceleration
  see Vivaldi Settings → Websites → Use of Hardware Acceleration
• broken browser cache
  Delete Browser Data Ctrl+Shift+Del → time range All → Cache
