Plasma freezing about krohnkite

[esjeon]

Sorry, I’m on a trip now, and will return on 6 Feb. I’ll look into this issue as a top priority once I return.

I think this maybe has something to do with geometry-restricted windows and krohnkite entering an endless loop of trying to set window geometry only to fail, which triggers change in geometry and causes krohnkite to try again. Just a speculation, but i do see a spam of similar messages in kwin log and xorg eats cpu 100% with kwin eating 10% or so.

[hjri]

I did some more screwing around and it seems like the problem only occurs with severely geometry-restricted windows and window padding enabled?

Window gaps: 16 between, 8 around.
3 apps: Slack, Riot, Quassel. All have sane geometry restrictions (window can get 300px-ish wide)
Everything works normally
2 apps: Cantata (sane geometry restrictions), System Settings (window refuses to go smaller than half a screen)
Kwin enters busy loop, there's spam of Krohnkite trying to resize systemsettings
Works fine

Window gaps: all zero
Both cases work fine

Disabling gaps entirely solved the problem, thank you. Additionally, using only outer gaps (set to 3, inner set to 0) I have not experienced any freeze.

I think your guess is correct. Krohnkite does have this problem. If both application and Krohnkite have different idea on what is correct geometry, they'll end up fighting each other.

It's likely that removing gap prevented Krohnkite from squeezing those windows too hard.

Anyways, it seems like this issue is related to issue #25 ("Resizing doesn't check for other windows' geometry restrictions"), which is a regression fixed by 31a7f30.

I still get freezes/spam even without gaps on e9bea92

Running kwin_x11 eventually gives spam like this.

@hjri, would you upload the whole log? I don't have enough information. Quassel limits only the minimum size (489x257), and, even when the limit is ignored, the application isn't supposed to freeze. It works flawless on my computer, for example.

after which there's just spam of thing i posted previously interleaved with badwindow/baddrawable which i think are unrelated to krohnkite.

also plasmashell is in ignored list because i was trying to debug another bug that made kwin freeze when plasma crashed.

[esjeon]

@hjri Hmm, I can't reproduce the bug. Would you file a new issue? I need version info and steps to reproduce the bug. At least, Quassel works fine on my up-to-date Arch installation, at it never tries to resize its main window.

[zyf0330]

Is there any update?

[esjeon]

@zyf0330 Sorry, the development has been stalled for a while. I'll come back to this shortly.

In the mean time, would you describe the specific problem you're having? Freezing is just a symptom, and can be caused by many different reasons. More info is definitely better.

[zyf0330]

Appreciate your work. I use KDE on Ubuntu. Open krohnkite script will cause freeze problem. After boot some time, kwin freezes intervally. It seems that longer I use computer, freeze time becomes longer too. I use google-chrome, slack, wine, tilix, webstorm, etc. Freezed parts include taskbar and everything at it and klipper list called by shortcut, not these app. Eon S.

IIRC workaround is to disable the "hide titlebar for maximized windows" script/option. KWin does have obscure option to do that without scripts but there's no GUI for it.

I had this problem and solved it somehow.

[zyf0330]

@hjri I will try, thanks.

[zyf0330]

@hjri This way almost solves this problem, you are right. Freezing still occurs sometimes but restores back to normal quickly.

[zyf0330]

After restart computer, freeze occurs. Everytime do plasmashell restart, freeze disappears a period of time then appears, there is no regular pattern.
