@SylwesterZ said in Wrong font rendering - very bad: I hoped that Vivaldi developers could fix engine bugs and shortcomings Please help develoeprs and report to Chromium bugtracker https://bugs.chromium.org/p/chromium/issues/list and to Vivaldi bugtracker at https://vivaldi.com/de/bugreport/

FYI, there are a few other (undocumented and unsupported) ways to fine-tune font rendering on macOS: How to Fix Blurry Fonts in MacOS Mojave for Non-Retina Displays http://osxdaily.com/2018/09/26/fix-blurry-thin-fonts-text-macos-mojave/

@tommytom2k2 Thanks for your information, very helpful for others.

Might be useful to prevent Vivaldi slowdown when open/loading multiple tabs together, & reduce rendering bottleneck problem for weaker PC.

@Gwen-Dragon I have filed a bug report and included all info I could think of. Thanks for your help.

Same, without problems Last version stable, Win 7 32
