Excruciatingly Slow Perf 1.7.1

[kumarab123]

Recently updated to the 1.7.1 official release. This doesn't seem to happen with jpegs, but if I develop a RAW (this is also much slower than before) and then maybe work for more than 3-4 minutes in the Photo persona, then the system starts crawling. It almost feels like a memory leak or something. Even if I manage to somehow close Affinity, the problem doesn't go away. The entire system crawls. I have to restart.

1.6.5 was snappy, really snappy. For clarity, by crawl I mean...click on a tab and wait 30 sec for the pull down, wait about 2 minutes for a simple curves merge. Should I just roll back to 1.6.5? My laptop; Win 10, Core i7 6700hq, 16gig RAM, GTX 960m.

If Affinity Photo is no longer running, then it can't be affecting your system. Can you bring up Task Manager after this slow down happens, and look what is using your CPU / memory / disk?

Nothing is running that didn't before. The task manager itself takes about a minute to populate after that. If I leave it be for like 3-4 minutes, then the laptop starts responding normally again.

As I said, it never happens immediately. It builds up over time. I have reinstalled Affinity to no avail. Happens with only the latest release version. 1.6.5 ran for hours without a single hitch. Everything else runs fine, Capture One, DaVinci Resolve, you name it. As it stands, it's pretty much unusable for anything but 30 second casual edits.

I have tried to narrow it down to a specific edit or filter that triggers it, but that seems to be irrelevant. It seems to be only dependent on time.
