xtermjs
Text selection highlight still remains visible after scrolling in the terminal
When I'm selecting a text in the viewport, after I scroll, a small highlight of the previous text still remains clinging on the viewport.
Had to fix it by providing this class:
.xterm-selection { overflow: hidden; }
I can't reproduce this, are you on the latest version (@xterm/xterm) and are you doing something atypical with the scrolling? For example are you creating a tall terminal and wrapping that with your own scroll bar?
For what it's worth, I saw this too. At first I assumed it was an intentional feature, but it seems to behave a bit weirdly (always shows up at the top even if the selection is scrolled off the bottom of the window). It's reproducible with minimal configuration: https://codesandbox.io/p/sandbox/xtermjs-test-forked-rfznf7

@Tyriar 遇到了相同问题，
1.如果使用HTML渲染方式，会出现灰块，一直悬浮在顶部，
2.如果使用webgl方式渲染，则会出现，最后一行，复制时选中行错乱问题（有尝试过增大行高依旧无效）
请给出解决方案，急！！！！
