IT editor spilling outside boundaries

[PMM_CAI]

Hello. This is a follow-up to an earlier ticket posted by someone about the same issue, but I didn't see a resolution there. Here's the link: https://forum1.pvxplus.com/index.php?topic=1001.msg3412#msg3412

I'm experiencing basically the same issue. When I hop from my IT editor to another window and then return, the loaded code is listed starting above the top boundary of the defined code area. Note: not every time, only some of the time. See attached screenshot.

Like the other user, this started after an upgrade. (In our case, we leapfrogged from 17 to 19.) We also have BX emulation on.
But unlike the other user, who used dark display, I use light.
We run PxP on a direct RDP session to our Win 2022 development server.
I want to reiterate: this is new behavior, in effect as of the new PxP version.

TIA.
