using vivaldi 1.12.955.48 for linux. while opening webpage there is flickering
there is persistent flickering while opening webpage. the same does not happen when using mozilla firefox browser.
closed vivaldi and restarted but issue persists.
Perhaps a setting with GPU/graphics card or driver.
Or may be a refresh/vertical sync problem.
I wrote a short article about such issue: https://labs.gwendragon.de/blog/Web/Browser/Vivaldi/slow-or-flickering-video-with-vivaldi-on-linux
