Scrolling not possible with some window-filling applications

[adrianghc]

Environment

Windows build number: 18362.267
Windows Terminal version (if applicable): 0.3.2171.0

Any other software? poolmon

Steps to reproduce

Start an application like poolmon from the Windows WDK that takes up the entire screen buffer while it's running.

Expected behavior

Under the normal Windows 10 terminal, I can scroll through it with the scrollbar and the scroll wheel.

Actual behavior

Using Windows Terminal 0.3.2142.0, there is no scrollbar and using the scroll wheel does not do anything either. Hovering over where the scroll bar should be makes it appear, but there is no actual bar, only up and down arrows.

(By the way, if anyone knows what's up with that PEPI memory leak you'd be my hero but that's another story, I guess.)

[DHowett-MSFT]

This is likely to be "conpty doesn't support mouse events" and then "windows terminal doesn't support mouse events." This is doubly true if the application in question actually listens for Windows mouse events (and not VT mouse events.). #376 #545

[Squall-Leonhart]

None of the changes mentioning this issue have fixed this issue, Poolmon is not scrollable when the buffer size exceeds the starting window height.

I don't think it has anything to do with the issues that were 'supposed' to be the cause, and a terminal developer should have a chat with someone on the DDK/WDK team that has access to the poolmon source to get a better understanding of the problem.
