Poor font rendering on tabs title

[podgrny]

Pixelated font on tabs title, address bar and bookmarks bar.

Vivaldi:

Brave:

Other than that, text in the sidebar, for instance, looks okay:

On 200% vivaldi UI scale fonts looks okayish:

Fedora 37, gnome, wayland

Disabling flags dont fix the problem. Fractional scaling is disabled. Font antialiasing set to subpixel & none hinting

@podgrny Welcome to Vivaldi!

I'm using the LXDE desktop right now. The current font settings are:

Antialiasing: Enabled
Hinting: Enabled (Hinting Style: Slight)
Sub-Pixel Geometry: RGB

The fonts here look fine with the above settings. The display (LED) resolution is 1920x1080. The GPU is an integrated AMD Radeon RS780L from 2011.

@podgrny also there are some errors in vivaldi://gpu

Compared to brave/edge the gpu internals page looks different, there is no ANGLE:

@podgrny
Hi, Brave is at Chromium 112, Vivaldi on 110, different results but many errors on both.
Pleas try the flag:
vivaldi://flags/#enable-vulkan
Some user report it fix the font rendering.

Cheers, mib

[podgrny]

@mib2berlin yep, tried. It doesn't work in my case and causes some artifacts occasionally, but thanks

@podgrny Vivaldi uses its own UI based on the despicable "web technologies" of the modern times (one solution for all OSes) and on CSS, so your best bet would be to search for something like increasing just the fonts size in those sections, and/or some other tweaks, in the mod section, if you don't want to use a UI scale of 110% for example. Brave on the other hand is just un-googled Chromium with no other features other than its own ad-network and crypto-shenanigans, so it looks like Chromium. You can see Chromium in Vivaldi as well if you run it in the terminal without its UI being run as an app with vivaldi-stable --disable-vivaldi.

@npro yeah, was thinking to customize font for tabs. But that's more like a crutch, rather than a solution. As for the cross-platform, on windows & macos everything looks nice, but as you can see cant say that for linux, fedora specifically. So for now trying search the root cause of it
