Additional Information:
I have tried various themes and display settings. This issue only appears to be affecting Brave. Vivaldi, Firefox and Chrome have no such issue…
Update: This behaviour only exhibits itself on Ubuntu. On my Windows the icons are normal size
@ConercaoNightly,
The address bar does seem to be slightly taller but I’m not sure what might be causing that. I see that you’re using the Bitwarden and uBlock extensions – can you tell me what other extensions you’re running at this time?
