Hi, thanks Basj!
Tried that, but it turned out there was a problem with graphic acceleration for certain plugins, namely the FabFilter ones.
Turned it off, and problem solved!
Couldn't really find anyone with the same problem, so if anyone is googling this, here you go:
"How can I disable graphics acceleration on my computer?
With some graphics cards and host software combinations, the GPU-accelerated graphics acceleration system in our latest plug-ins might cause problems. You can turn off graphics acceleration to find out if this fixes the problem.
Tip: If you experience problems, first try to update your graphics drivers to the latest version!
Windows: Click the Start button, type 'regedit', Enter to open the Registry Editor. (You might have to give permission to continue.) Navigate to HKEY_CURRENT_USER\Software\FabFilter. Right-click and select New > DWORD (32-bit) Value. Name it GraphicsAcceleration and ensure its value is 0.
Mac OS X: Open Terminal and type: defaults write com.fabfilter.Common GraphicsAcceleration 0
The above steps will turn off graphics acceleration for all FabFilter plug-ins. To re-enable it, change the value 0 to 1 in the steps above."
