I just wanted to add (as a new user of Brave) that as soon as I began to try Brave 0.61.52 today, I also met with this issue. I would describe it as follows — when opening a new tab with Ctrl+T (or the button) and then immediately typing one’s required URL into the address box, Brave displays the user’s input thus far, but then begins to open its pictoral screen during the time the user is still in the process of typing, but unfortunately, when the pictoral screen is complete, it erases the user’s input and in consequence the first part of the user’s input is lost.
Some of us are fast typists. A user who is slow to respond or slow to begin entering a URL is unlikely to be hindered by this.
For me it’s likewise a deal-breaker, as someone else mentioned, as I have difficulty with software that inconveniences me and in this case the picture screen is unwanted anyway.
