`pop_screen()` triggering randomly after hoovering buttons under heavy load

[matkudela]

I noticed strange behavior while hoovering very fast on many buttons. pop_screen is being triggered ramdomly only under heavy load on my computer (used stress command). Tried same thing with push_screen but works fine. Example used in video:

from __future__ import annotations

from textual import on
from textual.app import App, ComposeResult
from textual.binding import Binding
from textual.screen import Screen, ScreenResultType
from textual.widgets import Button
from textual.containers import Horizontal

class MyApp(App):

    def compose(self) -> ComposeResult:
        yield Button("next screen", variant="success")

    @on(Button.Pressed)
    def next_screen(self):
        self.app.push_screen(Screen2())

class Screen2(Screen[ScreenResultType]):
    BINDINGS = [Binding("escape", "other_screen", "next")]

    def compose(self) -> ComposeResult:
        with Horizontal():
            yield Button("1", variant="success")
            yield Button("2", variant="primary")
            yield Button("3", variant="error")
            yield Button("4", variant="success")
            yield Button("5", variant="primary")
            yield Button("6", variant="error")

    def action_other_screen(self):
        self.app.pop_screen()

MyApp().run()

My initial reaction to this would be that it's unlikely that it's a case of "pop_screen() triggering randomly after hoovering buttons under heavy load" and very possibly a case of an instance of escape being detected and processed as keyboard input.

[matkudela]

You are right, just tested it.

@matkudela Could you try running with TEXTUAL_DEBUG=1 to reproduce the issue, then sending us the keys.log file that it generates.

[matkudela]

You mean opening textual keys app? If no where I can find the logs?

[willmcgugan]

run your app with TEXTUAL_DEBUG=1 python myapp.py Reproduce the issue and exit. You should find keys.log in the working directory.

[matkudela]

keys.log

[willmcgugan]

You have a slightly older version of Textual. Would you mind upgrading to the latest, and repeating the test?

[matkudela]

Upgraded to 0.65.2, works same way keys.log

[willmcgugan]

I'm not certain if this will fix it, but please try 0.66.0

[matkudela]

Didn't help.

[willmcgugan]

Please try Textual 0.71.0

Most of the time works fine but managed to recreate this problem once in 15 minutes of testing.
