I would have accepted Kevins and your replies about the memory-usage as to be expected and have silently revert to 0.9.9, but as Kevin is asking to track this down, here are my observations:
I did a clean install of Sigil 0.9.12 64bit under Windows 7 64 bit classic theme.
Both program-folder and preferences were renamed ahead of installation.
Fireed up Sigil, loaded a epub, messed around with it.
Memory-Usage in task-manger remained stable.
Pressed F10, as with initial settings, Preview isn't shown. Did some more messing around, changing between open tabs, memory usage climbed and climbed.
This happed with and without using S&R. Just example searches like join paragraph. (no own settings are copied over).
Pressed F10 again, the memory-usage remained stable at the high level but didn't increase any further.
Then I did another clean install of your legacy build 0.9.12 using QT5.6 and wounder what? There is a stable low memory foot-print even with the preview Widget open.
You will find the same with any Sigil version using QT5.6.
(I'm just wondering about the statements the high memory usage while changing tabs would to be expected, but you are the developers, so it is not me to judge.)
So, beside of an possible problem converting *.inis to UTF-8, which I also noticed. Once changing all dashes to some weird 3 char code not alone in *.ini but also in the xhtml files in an open epub, I suggest looking into the usage of the preview Widget under Windows and QT 5.11.2.
For the time being I will roll with the legacy build.
Sincerely
Mark

I understand that many want to use Task Manager's reported memory usage as an indicator of a problem, but I'm really only interested in performance issues that are
experienced and not merely assumed by watching the "meter climb".
With the clean install and the default INIs, did you experience actual slowdowns? Did Sigil become less and less usable? Did you see any "Not responding messages", or did you merely see the numbers increasing in Task Manager?
I would really rather that testers leave Task Manager out of the equation completely.
I'm using 0.9.12 on both Windows 7 and Windows 10 and I have yet to experience any massive slowdowns or encounter any "Not Responding" messages. I'm not trying to brush reports off as "Works for me!" I know there are issues. I'm just trying to make it clear that that means it can't be as simple as Qt5.11.2, bad ... Qt5.6.2, good.
