Poor performance in editor after Windows 10 update. Specifically, dragging nodes in blueprint

Development Programming & Scripting Blueprint

I recently did a Windows 10 update (“Feature update to Windows 10, version 20H2”). Prior to this, I had no issues in the editor. Now, I’m noticing as I drag around blueprint nodes there is a very blatant stutter. Here’s a video of it happening: 2021 04 12 14 53 05 - YouTube . It’s more annoying than anything else, it’s not physically preventing me from doing anything but it’s aggravating. Any thoughts on what I might do to address this? I’m using a source built 4.26.

Edit: Ok, this is getting weirder. I have a scenario where I’m dragging off a pin and letting the context window pop up for suggested nodes to connect. However, the box is completely blacked out. I tried to record this with OBS to post here and … THE BOX SHOWS UP IN OBS. If I take a screenshot, it shows up fine in the screenshot too! I took a picture with my phone instead.

Here’s the screen taken with my phone:
And here’s the screen taken with a printscreen screenshot:

I mean … what???

Edit2: Further updates … this only seems to be occurring on one of my two monitors. And it’s not restricted to UE4 - seems even sometimes I’ll see behavior like this in windows in Windows Explorer. So I guess this post isn’t really about UE4 anymore …

Oh man, I can relate. Almost every other W10 feature update, something important breaks for me, but in such extremely rare and obscure way it leaves me wondering if it’s just me, especially when Google returns no results. I absolutely know the frustration.

Sometimes I even decide to do a complete fresh OS reinstall, just to know if it’s just my specific setup, and then carefully observe if it changed, or if it changes after installing other software back. But often, it’s same even after fresh reinstall.

It usually takes 2-3 months after each W10 feature update for things to finally settle down. It’s really frustrating that MS considers us voluntary beta testers, even in Pro versions of Windows.

So while my post probably did not help you with anything specific, I just want to say that I know these kinds of issues, and you are most probably not alone. :slight_smile:

Thank you, it does help to know I’m not alone with this. I did have something similar happening last year and I just gave up and did a full OS reinstall which actually fixed the issue. But I can’t do that every time …
