Pulsar Audio GUI Problems in Studio One

Hello,
i got a new pc, everything works fine so far, but the Pulsar Plugins (MU, 1178) have a GUI Problem. Sometimes the GUIs are showing when the plugins are loaded from the browser, but closing the GUI and reopening the error is still there.
I've tried several settings in IntelControlRoom, but nothing works. In Bitwig the Plugins are working, so it must be an StudioOne issue.
Latest drivers and VisualC Runtimes are installed.

Intel i7 12700K with Intel UHD Graphics 770
Asus Prime H670
Win 11 Pro 21H2

Maybe someone has a solution.

Try latest versions of Pulsar stuff, first versions were problematic with GUI etc. Now ok. Solved by updating to the latest versions, and also updated OpenGL drivers to the latest..

 

I have tested the two plugins, Pulsar Plugins MU and 1178, in PreSonus - Studio One v5.5.286528, tested everything works and there are no graphical errors.

 

Since both are even running on Win7 and SO v4.xxx, it's probably a broken installation.

 

I found the solution. I had to change in DeviceManager the driver from "Intel UHD Graphics 770" (latest) to "Intel UHD Graphics" (old from 23.07.2021) and disable in IntelGraphicControlRoom Antialiasing for Studio One.
I haven't a clue where the old driver is coming from, its a clean installation on a new pc. After Win11 installation i updated Win11, all drivers and BIOS with Asus and Intel Tools, after that i disable Internet. Maybe the old driver was installed with Win11. However - it works now.
Thanks for your advice.

 

Wonderful! Solutions are sometimes right in front of you.

For the driver update issue, it could be the notorious Windows Automatic Driver Update. A possible solution:

This is what I have done for all of my Windows 10 systems with Intel or NVIDIA graphics. Has also prevented network & USB random errors from occurring.
