Seems to be specific to the Linux build of the game; this does not occur in Windows or when running the Windows build on Linux using Proton. All three situations were tested on the same hardware.
Selecting things and then interacting with the game by dragging the mouse (middle-click drag the map to pan, left-click drag the map to select, left-click drag stockpile sliders and wiggle the mouse quickly, etc) causes significant stuttering and freezes. This is worst when panning the map - selecting a single grow zone and panning the map is noticeably stuttery; selecting multiple and panning causes long freezes (the longest I have a specific number for was 60.7 seconds; I have definitely experienced multi-minute freezes in the past, and I suspect they were caused by this issue). Panning the map using the arrow keysdoes not display the issue edit: only shows the issue with grow zones selected, not with rock chunks???.
Happens in all saves, at all times, both modded and vanilla.
The easiest way to reproduce this issue is to start a new colony, zoom out and double-click a rock chunk to select 100-200 of them, then drag a new selection box or pan the map with the mouse.
Pretty sure the logs don't have anything useful, but here's a log where I started the game, started a new colony, then triggered the issue
Possibly related, but may be separate: relatively slow mouse movements seem to be ignored by the game - if I e.g. drag a selection box or UI slider quickly, then slow down and move the mouse slowly, I can get the mouse to move without changing the selection box or slider. This situation only resolves itself when I move the mouse quickly or release the left button.
If I do this with a selection box while grow zones are selected, any mouse movement that doesn't cause visible changes to the selection box doesn't trigger the stutter/freeze.
(This slow-mouse-movement issue is also Linux-build specific; it does not happen in the Windows build, either on Windows or using Proton)
