Black and Yellow pattern on some downloaded Scenes

[VinoChino]

I got this problem since I bought WE years ago and i thought it was the projects that had something wrong with them, but maybe its just some setting thats wrong or a bug.
Looks like this: https://i.redd.it/30803dh9u8k11.png
WE is updated, so is Win10 and gforce drivers. I also noticed that while creating a new scene it shows me the same pattern for the Shake effect https://i.imgur.com/XhlNuPZ.png instead of the WE logo it should show.
Oh and when I try to add a shake effect the cursor becomes so extremely slowly that its impossible to aim. This particular problem came somehow over an update 3-4 months ago.
Any advise?

Have the same kind of problems. Sometimes when i check a new wallpaper the black and yellow patterns flash and it looks like WE is compiling some textures but then it never comes to an end and keeps flashing for hours.
I guess it has something to do with the nvidia driver which is a total mess in my opinion if you want to do something other than gaming. I have a second PC with a nice AMD gpu and none of the problems ever happend on that machine. Sadly i don´t know how to fix this, maybe the developers can take care of it?

I closed WE from tray and it updated through steam. Normally it does that when i open the WE GUI but not this time. I also tried one of the projects that I know that this would happen. And suddenly it works. I also had a reddit thread and some ppl there also mentioned a reinstall is the solution. Didnt fix the shake effect lag though

The yellow-black checkered pattern is indeed always related to either broken files or missing Wallpaper Engine updates, the easiest way to fix it would be to verify the software files via Steam:

The Shake effect itself should only be laggy if your computer is too weak to handle it. Make sure you have no screen recording software or similar running which may cause performance issues like that, especially some Nvidia game streaming features in the Nvidia GeForce Experience application can cause this.

Hardware should'nt be the problem, I run a 6700k and a 1070gtx. I noticed the lags appearence month ago so I'm absolutely not sure when it began, and its only the shake effect. Nvidia shield streaming is deactivated. I dont have anything running that would cause such ressource leaks. CPU usage while painting the shake peaks around 25% cpu. I only got a few apps in my tray: rainmeter, driver for logitech, driver for audio xblaster, steam, discord, nvidia.

I literally closed all applications that are running in the background. I even closed nvidia and keyboard/mouse driver software. There's still the lag with the shake effect when painting. No idea what I could try now other than reinstall windows, which is not an option just because of this lag.
