The MATLAB Editor in R2021b is less responsive for some Linux users. This can be seen with some basic operations like typing and scrolling, which can be noticeably slower than previous releases. How can I resolve this issue?

Disabling hardware acceleration is observed to resolve the latency issue. Try opening MATLAB using the '-cefdisablegpu' flag as follows.
$ matlab -cefdisablegpu
