2023-03-19 20:03:51 <dge> ok, i get a compilation error after to try from stack recompile.... due to version between ghc and stack (8.10 for ghc and 9.2.7 from stack) that is bad. I have to upgrade stack, but missing space on VM disk (crying)...

2023-03-19 21:43:10 <Guest1886> Having trouble with an app stealing keyboard focus. Reproduced this with a minimal xmonad config (i.e. just `import XMonad; main = xmonad def`). Repro: with the minimal config launch Godot4 (stable), and switch to a terminal with `modmask+j` then resize window with `modmap+h` and observe that keystrokes go to the Godot4 window even though the
2023-03-19 21:43:11 <Guest1886> terminal's borders are highlighted. I'm running latest ArchLinux:

2023-03-19 21:44:23 <geekosaur> you're saying the xmonad keys are going to the app?
2023-03-19 21:44:34 <Guest1886> all keys are going to the app
2023-03-19 21:44:43 <geekosaur> that requires it to have done a key grab, which we can't prevent
2023-03-19 21:44:50 <Guest1886> xmonad keys still work

2023-03-19 21:45:00 <geekosaur> oh
2023-03-19 21:45:31 <Guest1886> It doesn't happen in e.g. Ubuntu 22.04 (with alt-tab)
2023-03-19 21:46:28 <Guest1886> i.e. with Ubuntu's stock window mgr and desktop
2023-03-19 21:47:02 <geekosaur> have you tried it with xmonad on ubuntu? or with a different window manager on arch?
2023-03-19 21:47:36 <geekosaur> we've had problems with arch's packaging of Haskell stuff (and in particular xmonad) but this would be somewhat weird
2023-03-19 21:48:45 <Guest1886> I tried xfce and lxde on arch and saw the issue randomly on lxde (alt-tabbing) but not on xfce. I'm trying xmonad in Ubuntu next
2023-03-19 21:50:54 <Guest1886> This is a related issue for Godot https://github.com/godotengine/godot/issues/74587 but it isn't really getting any attention leading me to think that not many people are seeing it. So I'm not sure what software has the issue.
2023-03-19 21:53:02 <Guest1886> As above, I reproduced with min config but I noticed that the problem is much more aggressive with my full config, notably with bluetile (i.e. grabs keyboard more often and much harder/nearly impossible to get keyboard focus back even when clicking mouse on intended window)
2023-03-19 21:53:11 <geekosaur> sounds like that's actually two issues, an earlier Windows-specific one and a more recent one that repros in lxde and i3
2023-03-19 21:53:18 <geekosaur> and, apparently, xmonad
2023-03-19 21:53:55 <geekosaur> the i3 reproduction is 3 days old
2023-03-19 21:54:18 <geekosaur> which means just before the weekend so probably nobody sees it until tomorrow 🙂
2023-03-19 21:55:17 <Guest1886> yes, I was thinking more of a general issue originally with the windows problem but since it didn't show up in Ubuntu (stock WM) or Arch XFCE it seems like the windows issue might be unrelated and that the i3 and xmonad issues *might* be caused by similar implementations (??)
2023-03-19 21:55:56 <geekosaur> well, we're both tiling, but that doesn
2023-03-19 21:55:59 <geekosaur> 't explain LXDE
2023-03-19 21:56:30 <geekosaur> I'd be curious as to whether it also happens with LXQt (same environment different implementation)
2023-03-19 21:57:12 <Guest1886> I'll test LXQt in Arch too
2023-03-19 21:57:15 <geekosaur> in any case it sounds like it's stealing focus
2023-03-19 21:59:09 <Guest1886> So I don't know much about X11 implementation but it sounds like client windows can choose to steal focus, overriding any focus controls implemented in window managers?
2023-03-19 21:59:23 <geekosaur> (LXDE is Gtk based, LXQt is part of a long term move from Gtk to Qt)
2023-03-19 21:59:30 <geekosaur> yes
2023-03-19 21:59:42 <geekosaur> it's strongly frowned upon
2023-03-19 21:59:51 <Guest1886> gotcha
2023-03-19 22:00:43 <geekosaur> but the same API is used for a program to set focus to an internal widget so they can't simply remove it
2023-03-19 22:07:45 <Guest1886> btw I found running `watch -n0.1 xdotool getwindowfocus getwindowname` useful for debugging this
2023-03-19 22:08:50 <Guest1886> just prints the currently focused window and the bug can be seen when it prints the Godot window name while xmonad is highlighting a different window

2023-03-19 22:28:11 <Guest1886> LXQt on Arch behaved the same as LXDE did
2023-03-19 22:30:20 <Guest1886> However there is a difference between what LXDE/Qt are doing and what XMonad is doing. LXDE/Qt keep correct window highlighting but XMonad doesn't
2023-03-19 22:32:15 <Guest1886> i.e. in the video ( https://github.com/godotengine/godot/issues/74587#issuecomment-1466538062 ) at 15 seconds you can see alt-tab to terminal fails but the Godot window keeps the highlighting. But when in XMonad the terminal I wan't to type in gets highlighted but the keystrokes keep going to Godot
2023-03-19 22:33:20 <geekosaur> hm. normally xmonad should get the focus change event and update the borders
2023-03-19 22:35:23 <Guest1886> Yes that's what's making think that at least part of the prob is in XMonad
2023-03-19 22:45:39 <geekosaur> https://paste.tomsmeding.com/Cx907lfH
2023-03-19 22:46:21 <geekosaur> then check the session log when this is happening. it should show either or both of FocusChangeEvent or CrossingEvent happening
2023-03-19 22:46:38 <geekosaur> (probably FocusChangeEvent since the mouse isn't causing it_
2023-03-19 22:46:41 <geekosaur> )
2023-03-19 22:48:02 <Guest1886> Will do
2023-03-19 22:48:43 <Guest1886> Also just confirmed bug occurs in Ubuntu 22.04.2
2023-03-19 22:49:07 <Guest1886> xmonad 0.15
2023-03-19 22:49:11 <Guest1886> totally default
2023-03-19 22:51:25 <geekosaur> the other alternative is you'll see a whole bunch of them, which would mean xmonad is indeed trying to track it but it's fighting with godot4 and you can't see the focus changes because they're happening too quickly
2023-03-19 22:52:04 <geekosaur> although in that case this might slow things down just enough to make them visible
2023-03-19 22:57:03 <geekosaur> one other thing to try is to enable EwmhDesktops and see if it still happens. for backward compatibility reasons we don't support EWMH by default, only ICCCM

2023-03-19 22:57:31 <Guest1886> Tried `import Data.Semigroup.Internal` also
2023-03-19 22:57:38 <geekosaur> but this breaks a number of modern programs (for example, LibreOffice will get into a focus loop without EWMH)
2023-03-19 22:57:48 <geekosaur> oh, sorry, need to import Data.Monoid, forgot that
2023-03-19 22:58:00 <Guest1886> yeah I normally use EWMH and still saw the bug

2023-03-19 23:00:37 <geekosaur> (…Data.Semigroup.Internal? It doesn't make any sense as a semigroup, it needs `mempty`)
2023-03-19 23:01:00 <geekosaur> guess they have weird organization for those modules
2023-03-19 23:07:54 <Guest1886> Which log should I look at? ~/.local/share/xorg/Xorg.0.log and /var/log/Xorg.0.log don't seem to have anything

2023-03-19 23:08:52 <geekosaur> session log
2023-03-19 23:09:03 <geekosaur> for startx it'll be the text console
2023-03-19 23:09:17 <geekosaur> for display managers other than sddm it's ~/.xsession (usually)
2023-03-19 23:10:06 <geekosaur> for sddm it's ~/.local/share/sddm/xorg-session.log
2023-03-19 23:10:30 <geekosaur> sorry that was ~/.xsession-errors

2023-03-19 23:11:48 <Guest1886> ok I use startx... trying to find the magic ctrl-alt-f# key...
2023-03-19 23:12:04 <geekosaur> should be ctrl-alt-f1
2023-03-19 23:12:47 <Guest1886> yeah I expected that but only >1 are working (new logins only)
2023-03-19 23:13:03 <geekosaur> although for some reason I've never understood that doesn't work on ubuntu, I always have to ctrl-alt-f2 and then alt-f1

2023-03-19 23:31:48 <geekosaur> did you survive?
2023-03-19 23:34:12 <geekosaur> odd, looks like you killed it with ^C?
2023-03-19 23:34:26 <geekosaur> no focus changes logged, at least
2023-03-19 23:34:57 <Guest1886> yeah... startx wouldn't work while `script` was running so I just did `startx &> log`
2023-03-19 23:34:58 <geekosaur> so whatever godot is doing, xmonad isn't being informed of it by the server 😞
2023-03-19 23:38:39 <Guest1886> Also, I had to start xmonad/startx with my usual config then reload to your debug config in-session. When I started with the debug config I had no input at all and had to `killall xorg` from another console.
2023-03-19 23:39:16 <Guest1886> I didn't see any obvious xmonad debug output in my pastebin, just the usual reload stuff
2023-03-19 23:39:43 <geekosaur> it should only have been logging focus change related events
2023-03-19 23:40:07 <geekosaur> I could have had you run debugEventsHook unconditionally but that would produce a lot of spam
2023-03-19 23:40:34 <geekosaur> that thing about the debug config sounds very wrong
