tsserver.js using 100% of CPU

[LeeCampbellr]

Issue Type: Performance Issue

Whenever I open a Gatsby.js project and run gatsby develop the electron_node tsserver.js process takes 100% of the CPU. I read some github issues and deleted my typescript 3.4 cache folder and that resolved it for about an hour then it starts again. It immediately turns on my fans and drains my battery

Same issue on my angular/typescript application. Git in the editor is hanging. Delaying on commits and pushes if not processing them at all.
