Transparent Context menu in PhpStorm missing contents

[wlightning]

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

As for your questions:

What happens connecting just the DisplayLink screens

Answer: Issue goes away (only one screen at that point)

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?

We have a reproduction!

Next, analysis. Still unsure whether it's an OS bug and/or we can do something about it.
Will update as soon as we find more information.

Excellent. Thanks!

Looking forward to your next update.

We checked the multiple GPU theory with an external GPU (eGPU) and we can reproduce there as well. This definitely puts the issue in Apple's court so we're going to open a bug on bugreporter. We'd suggest you to open a bug with Apple too, on bugreporter or on the normal support channel if you are not a developer.

In terms of workarounds this is very tricky indeed. Let's see if we can come up with something that does not cause issues elsewhere.
