1. Enter a long line of Chinese characters at random to ensure that a horizontal scroll bar appears

2. Scroll the scrollbar to the far right.

3. Cursor to the current line anywhere except the last, enter any Chinese characters, you will find that the current line of abnormal flickering (sometimes shorter text will also appear this problem, but I can only 100% reproduce this situation)

Also, I noticed that when typing Chinese characters, the highlight border breaks at a different position。Below is a different representation of Monaco and vscode ：
