Terminal Sticky Scroll causes incorrect screen size detection for scrolling

[sparr]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.106
• OS Version: Arch Linux current

Steps to Reproduce:

1. have sticky scroll enabled automatically by an upgrade
2. run a terminal command to produce a lot of output
3. press shift+pgup to scroll up
4. observe you have scrolled up far enough to miss two lines of output, the two lines hidden "under" the sticky scroll
5. clear the terminal
6. run a terminal command that clears the terminal and produces exactly one screen of output
7. observe that the top two lines of output are hidden by the sticky scroll, and shift+pgup or scrolling with the scrollbar have no effect because you are already at the top of the output counting the hidden output.

Thanks for creating this issue! It looks like you may be using an old version of VS Code; the latest stable release is 1.107.0. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

@sparr Thank you for the issue. Do you mind sharing a gif showing your command? They would be helpful, thanks :)

Here is a screenshot of the problem in action. I have just typed git log and pressed enter. The git-log application believes it is showing me lines 1-13 of its output on a 14-line terminal (with the 14th line for the lines 1-13 footer), but the sticky scroll is obscuring the top two lines. Pressing up-arrow or page-up has no effect because the application believes it is already scrolled to the top of its output and showing me the first line of the file. Pressing page-down scrolls the output to lines 14-26, because it believes it has a 13 lines of output space, but again the top two lines are not visible, and continuing to scroll down by pages will cause me to miss 2 out of every 13 lines.

this is the closest issue I could find to something that happens to me as well. often, but not always, running git commit has a terminal sticky scroll obscuring the first line which causes me to have to resize it to get rid of it. visual gif example:

(extra info: even after resizing it back down, the terminal sticky scroll does not appear again)

it slows down my workflow especially when I'm in a flowstate and basically freezes me for a good 5 seconds since I have to use my mouse and not just my keyboard
