Attached is a recording of it happening. It also is inconnsistant, but happens often.

As for your questions:

Quote:
What happens connecting just the DisplayLink screens
Answer: Issue goes away (only one screen at that point)

Quote:
changing the main screen in the arrangement tab in the Displays system preference (by moving the menu bar)
Answer: If the main screen is set to the USB display, the USB display ceases to have issues, however then the other (pass-thru USB-C) screens start presenting the same issues.

Some other scenarios I tried:

Only native/passthu displays (2 displays)
Issue does not present itself in any way.
Only native display
Issue does not present itself.
One USB display + native display
Issue presents on whichever screen is not main.
Passthru/Native/USB with USB set as main
You'll not only see phpStorm issue on Passthru and Native, but tearing of other graphics too... minimizing from USB screen tears across the Chrome screen in the Passthru.
Thoughts:

Maybe this is related to windows rendering to multiple displays on different graphics cards?
