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