Brave - latest version
Monitor 1: 3440x2560 21:9 widescreen
Monitor 2: 1920x1080
When using brave with flash, video, or music playing on that tab and moving it from Monitor 1 to Monitor 2, the widescreen aspect stays and the video/flash/music freezes.
After refreshing to fix the monitor issue, if you move it back, from monitor 2 to monitor 1 – the issue reoccurs.
The only way to fix this is to refresh the page.
