Significant UPS drops when quickly hovering over entities

[tux_mark_5]

Hello,

I'm playing a modded game with around 145 Factorissimo surfaces. The game runs fine most of the time (60/60), but it sometimes stutters.

I've noticed that stuttering happens when I move my mouse across different entities. Quickly moving mouse around entities (of any type) causes "Chart Refresh" to take the vast majority of the update time. The debugging option shows that "Chart update" normally is around 0.2 ms, but it rises to 10 ms with peaks of 25 ms when quickly moving mouse around various entities. This causes quite visible and annoying stutter. The rest of the game takes 7 ms to update even with all the mods included. The problem seems to get worse the more surfaces there are. I have several saves of my game and the Chart Refresh time rises seemingly linearly with the amount of surfaces used.

Is this the intended behavior? As right now it seems that Factorio keeps traversing all the surfaces for some reason as soon as I hover on some entity.

Factorio version: 0.15.32

Can you post a list of your mods?
Did This happen in .15.31 or earlier?

Might want to also post your save and modfolder to dropbox/googledrive and link it here.

This definitely happened with 0.15.31. If I had to guess, I'd say it happened with older versions too, but I can't 100% be sure as I never had this many surfaces in a single game.

EDIT: I've just checked an different older save with 0.14.22 and the issue seems to be present there as well. However the Chart Refresh only rises to 2 ms there. But that game has quite a few less of surfaces.

Thanks for the report. I found the cause of the problem although it only shows significantly on Linux apparently.

Anyway, it's now fixed for the next version of 0.15 (if there is one) otherwise it will be fixed in 0.16 as well.
