I have the same problem with Quartus 18.1 on a MSI laptop with a Nvidia GTX1660Ti graphics card. My issue though differs from yours as follows:

  1. Platform Designer does this with all qsys projects.
  2. The problem manifests on my laptop screen when I connect a second monitor.
  3. When I move the Platform Designer GUI window to the second monitor, the problem initially disappears on that monitor but reappears later.
  4. The Quartus Prime Standard Edition GUI window has no problem on either of my monitors.
  5. Temporarily unplugging the 2nd monitor HDMI cable and reattaching it, sometimes resolves the problem but only for a short duration or until I recompile the qsys design and the scripts start running in the pop-up window.
  6. The issue manifests when the mouse pointer crosses the panel border lines inside the Platform Designer GUI (the ones you use to adjust panel window sizes) or touches the U-D/L-R scroll tabs.
  7. When the mouse is dragged from R-L or L-R across the vertical panel window borders, this does not seem to occur.

I also have a laptop with a 2nd monitor, but the problem occurs on both monitors and with the external monitor disconnected.

I have Intel UHD Graphics 630 & NVidia GeForce GTX 1050 Ti.

An FAE suggested changing the setting as shown to fix issues with 4K displays, but this didn't resolve my problem.
