If you are experiencing crashes or memory leaks on macOS 10.14.4, please try changing the gpu_window_buffer setting in Preferences to false, and then restart Sublime Text. Example settings:
{
"gpu_window_buffer": false,
}
Unfortunately it appears that Apple’s NSOpenGLView is rather buggy in 10.14.4 and can easily lead to crashes with DisplayLink adapters, eGPUs, some graphics cards and in other unconfirmed situations. Disabling the gpu_window_buffer optimization works around this issue until 10.14.5 is released.
