Progressive slowdown - Fixed by installing KB4058258

Using the new beta and it does seem to handle notifications nicely.
On the exact same day I installed it however - the slowdown happened again and at my wits end, I found this article.

Namely:

Ever since the so-called Fall Creators Update of Windows 10 (version 1709), Adobe Lightroom Classic CC has been suffering from what I believe to be the GDI GetPixel() bug

The symptom is that UI performance degrades gradually as Windows remains up, and only a reboot of Windows restores correct performance. Switching modes and tools (in Programs) results in very slow screen repaint after a few days of Windows uptime.

For anyone having this issue (probably everyone on Windows 10), this update seems to fix it:

After manually installing the mentioned KB4058258 as winupdate refused to offer it to me by itself - so far all is good.

I'm positive this same bug was the one affecting dopus as like I mentioned before - the toolbars were gradually painted, lister redrawing was slow and erratic, focusing - unfocusing, and even filtering preferences made the results appear sequentially with visible lag between them and not instantly like on a fresh restart.

As it turns out the problem was on a lot larger scale than DOpus and I feel bad for making conclusions.
Fall creators update really did a number on us - until this update - hopefully.

To check if you have the update installed:

  1. Open RUN (WIN+R)
  2. Type winver, hit enter
  3. Look at the version string - it should read Version 1709 (OS Build 16299.214) or higher
  4. If it's lower check windows update or install the KB update above.
  5. If it's equal or higher and you're still experiencing the slowdown - then it seems we're not in the clear yet.
