Slow, Laggy typing

Hello!

Please install CLion 2020.2 EAP (https://www.jetbrains.com/clion/nextversion/) and try using it. Note that you don't need to uninstall the stable version in order to test the EAP build, they can be installed side-by-side.

Also please enable memory indicator (а right-click at the bottom right panel > Memory Indicator) and keep an eye on it for some time. If it is close to the limit at the time when you are experiencing the problems, then try increasing the Xmx JVM option according to this guide.

If the situation is still bad in CLion 2020.2 EAP with enough heap memory, , please send us automatically generated thread dumps if you have them in the logs folder (Help | Show Log in …) or capture a new CPU snapshot and send it to us. You can send the materials to clion-support at jetbrains.com.
