Turning kwin-tiling on makes KWin crash often

[piotr-dobrogost]

After I turned kwin-tiling on Kwin keeps crashing often. Although I installed all available debug symbols ([Install Debug Symbols] button in Crash Reporting Assistant) I can't report issue as I get This crash information is not useful enougth (…) error. I'm attaching traceback I have at the end of this post.

In addition, after turning kwin-tiling on, KDE/Plasma/KWin becomes unresponsive for quite long periods (from a few to several seconds) and generally desktop becomes unusable due to windows not refreshing and/or not changing size properly.

kwin-tiling 1.4 KDE 4.12.2 Fedora 20

I have one desktop and two monitors.

Traceback which is shown in CRA looks like this:

Application: KWin (kwin), signal: Segmentation fault

[faho]

I'll have a look at it tomorrow. In the meantime, please don't report this to kwin upstream, I have an idea what it might be caused by and it would be my fault, not theirs.

[faho]

So, this is probably caused by one of three things:

• Bugs in the decoration or our interaction with it
• Bugs in our multimonitor code (rather likely, considering I barely tested it)
• The hack I've just removed in 9b8b91a

Can you please try the latter?

[piotr-dobrogost]

Do I have to restart anything after installing new version of the script?

[faho]

Yes - kwin --replace should suffice.

[piotr-dobrogost]

After installing 9b8b91a things got better. I did have a few crashes but they are much more seldom. Also windows are more responsive now. If you want I can send traceback next time KWin crashes again.

[faho]

Tracebacks would be nice, but I'll close this issue once I merge the 15 branch as I think the new crashes are unrelated - can you test the new HEAD of that?

[piotr-dobrogost]

I can test whatever you need to be tested. However I'm not sure which head you you refer to.

[faho]

Oops forgot to push - I'm referring to 0dd06bb67da0aa3194186d86798bbd49cad346ec (now in master as I merged already). This one has an attempted fix for what the removed hack tried: Prevent clients (like vlc) from becoming corrupted when their min/maxSize is violated.

[piotr-dobrogost]

And what steps are needed to verify the fix?

[faho]

See that it's no worse than 9b8b91a. If you want to do something extra, see that it does what it's supposed to do:

See that Firefox doesn't size weirdly (i.e. not filling the entire screen) when launched

See that vlc, when playing a video, then switching to no-interface (CTRL+H), resizing it to something small and switching the interface back on (CTRL+H) doesn't "hang" (i.e. not change the display) unless resized back to an "acceptable" size.

[piotr-dobrogost]

Start situation: Firefox maximized and occupies whole screen.

1. Launch vlc; Firefox is being resized and takes left half of the screen, vlc takes right half of the screen.
2. Start playback in vlc; vlc resizes itself to fit the video format, elapsed time is stuck at 00:00 and there's only audio (no vision).
3. Maximize vlc and restore it; now it takes right half of the screen again, and video is shown in the center.
4. Press ctrl+h, grab lower right corner of vlc window to resize, resize to small size; the moment left mouse button is released vlc window resizes back to half of the screen.

[piotr@demon ~]$ kwin --version
Qt: 4.8.5
KDE Development Platform: 4.12.2
KWin: 4.11.6
[piotr@demon ~]$ vlc --version

[faho]

vlc resizes itself to fit the video format

Well, I think this is an option that's kinda against tiling, so I'd be okay with breaking it if the only option is breaking numerous other cases.

the moment left mouse button is released vlc window resizes back to half of the screen.

Oh, you'll need to resize another window as KWin won't allow resizing below minSize - I'm not sure what to do about that, though.

In summary: This fixes your crashes and retains the same behaviour as the previous hack, so I'm calling it fixed for now (in git, I may do a release sometime soon).

[piotr-dobrogost]

Oh, you'll need to resize another window as KWin won't allow resizing below minSize - I'm not sure what to do about that, though.

How do you know I resized below minSize? Is minSize global or per window? If the latter do you know minSize value for vlc?

In summary: This fixes your crashes and retains the same behaviour as the previous hack, so I'm calling it fixed for now (in git, I may do a release sometime soon).

Thank you for fixing this.

[faho]

Is minSize global or per window?

Per-window. It's something the client can request.

If the latter do you know minSize value for vlc?

xprop, click open vlc window, see something like

program specified minimum size: 613 by 81

though it could also change and depend on e.g. the video being played.

Thank you for fixing this.

Unfortunately, I just found out that it doesn't quite fix the corruption (see small dolphin windows), though corrupt windows are better than crashes.

[faho]

So, it seems like there is more to this than I initially thought.

Can you give me the following things:

• your ~/$(kde4-config --localprefix)/share/config/kwinrc
• your videodriver
• your window decoration

and any other information you might think useful.

[faho]

Please try 1aded34cb6376eb01aaff2427b27. My new suspicion is that violating min/maxSize is breaks kwin, so this commit changes it so we don't do that anymore.

[faho]

Can you confirm that v1.5 (i.e. 1aded34) doesn't have this anymore?

[piotr-dobrogost]

I remember about this issue and will test it later today. Sorry for delay.

[piotr-dobrogost]

Well from the quick look it seems like things do not look ok and I managed to get a crash too. I see pretty wired behavior in some circumstances and need more time to describe them here. Btw, I think it would help if we could start gathering some test scenarios so that we know what we really test. This would allow for testing regressions, too. It would be best to find some tool to automate these tests…

[faho]

Well from the quick look it seems like things do not look ok and I managed to get a crash too.

Ah crap. I've run this version for two weeks without problems, including occasional torturing.

Is it the same crash (i.e. in KWin::Client::layoutDecorationRects)? What's your window decoration?

This would allow for testing regressions, too. It would be best to find some tool to automate these tests…

I've thought about it, but I'm not quite sure how it's supposed to work. Just launching clients wouldn't be enough, we'd need a tool to essentially "robotize" X11, something like autokey might suffice.

[piotr-dobrogost]

Is it the same crash (i.e. in KWin::Client::layoutDecorationRects)? What's your window decoration?

Yes, it's the same. I have default window decoration – Oxygen.

Okay, it works for me with your kwinrc (and I also use Oxygen).

Did you specify any kwin rules (i.e. is there anything in kwinrulesrc?)

As to videodriver I do not know how to check this.

lspci -vnn, look for "VGA compatible controller" and the line "Kernel driver in use".

For the record, this is my kwinrc:

Bump?

How's current git master (i.e. f60457f4e28d92629d9fd50f8bbb619a8c0e22f9)?

[greeny277]

Sometimes when I click on maximize/minimize button in tiling mode kwin freezes. Where can i find traceback on another tty. Kwin dont show any error messages after restarting lightdm. Accordingly to this i didn't find any usable messages in /var/log/* or ~/.xsession-errors.

[faho]

So, first of all, that's a different bug (freezing vs crashing). Please file a new issue.

Secondly, you should enable all debug output in kdebugdialog and then check .xsession-errors again. I'd also like to know your kwin version (kwin --version) and distribution, graphics hardware etc. (Unfortunately freezes are the kind of thing where it's likely that you won't get any output)

Since I haven't seen any more indication that crashes are happening and haven't been able to reproduce it myself, I'll close this bug. (Of course, if you get crashes, feel free to reopen this one or file a new one).
