Vlad Hi, I am using version 0.99.123.1-beta, but the issue is still present. As vladstudio explained, it happens when you use a normal tab right after a pinned tab. Then, when using other normal tabs going further right, it disappears. Even when going back to the tab with the visual glitch, it does not have it anymore. But then, going back to a pinned tab, and then back to a normal tab right after a pinned tab, it appears again.
