Dolly Camera twitching on different resolutions

Hi! So... I have a Dolly Camera with Track, the camera looks at the character and follows him with auto dolly function (I'm trying to make a 3D platformer, where my character follows a certain path while the camera follows him on its own track... and I used Cinemachine for that, cuz it was easy to set up). Cinemachine brain update method set to smart (by default), path resolution and dolly camera settings set to default too.

I have a set of different resolutions (mostly 16:9 - 1920 * 1080, 2560 * 1440, 3840 x 2160) for some performance tests and... Well, with 1440p or 2160p camera follows the track & looks at the character perfectly smooth. But when I switch to 1080p (or any other resolution less than 1440p) camera starts twitching a bit at random moments while following the path, it looks like in these moments it changes the position momentarily instead of smooth transition. How can I get rid of it?

 

Both, in the editor and with a build, and it twitches in both cases on resolutions lower than 1440p. It might be less in the editor, but I can't say for sure cuz it happens at random places.

 

I turned all vcam damping settings to 0 and this twitching still occurs (but it looks more like stuttering when the camera moves in an arc of the track, and less like a single random twitch here or there).

If I set Body's Z damping to 0, and X and Y damping to 0,5, there's less twitching (almost none in the editor, but still some in the build, a lot more in the build if Z damping is set to 1) if I start the game in 1080p. In 1440p or higher all looks fine & no twitching in the build with these settings.
