I had a similar issue. Turned out to be caused by a mercurial repository I had (for some reason) in my main development directory where I have all my projects. Although this occurred before the 2.0-rc.23 release, so it might be something else.

I have also been noticing this. Just moving the cursor around in medium-sized Python files (like beginnng of line / end of line) and I'm seeing stalls and very high CPU usage by the process.

Hi,

I experience lately on a regular base a high CPU usage of TextMate (TextMate
version 2.0-rc.23, macOS 10.14.3 18D109). I did not install new plugins
(besides of regular updates TM-build in plugins). TM does not crash so I
cannot provide a crash log.

Could it be related to performing a search in a project folder with a large
number of files?
