Display not being refreshed after App.suspend (since 0.85) #5528
Description
Using this code:
from os import system
from textual.app import App, ComposeResult
from textual.containers import Horizontal, Vertical
from textual.widgets import Footer, Header, Input
class SuspendingApp(App[None]):
CSS = """
Screen {
Vertical {
border: solid;
}
}
"""
BINDINGS = [("f1", "edit")]
def compose(self) -> ComposeResult:
yield Header()
with Horizontal():
yield Vertical()
yield Vertical()
yield Input()
yield Footer()
def action_edit(self) -> None:
with self.suspend():
system("vim")
if __name__ == "__main__":
SuspendingApp().run()
if you press f1 and then exit vim the screen of the Textual application doesn't fully restore:
Screen.Recording.2025-02-15.at.08.58.26.mov
Working backwards through Textual releases, the last version where App.suspend worked as intended was v0.84; it very much appears that v0.85.0 introduced this issue.

Joining the dark side Dave?
git bisect points to 6298acb, presumably this change in screen:
I'm not really familiar enough with how the refreshing works to say this is the correct fix, but just sharing my findings in case it helps someone...
