Comment 1 Raghavendra kamath 2018-12-11 06:15:10 UTC

On further inspection, this only happens when I use pen and not with mouse

Comment 2 Halla Rempt 2018-12-11 07:47:57 UTC

If you're still on Arch Linux, try to rebuild Krita. The crash goes through the lut docker, so it sounds similar to the problem someone on irc had, last night, where things got broken because libopencolorio was removed somehow.

Comment 3 Matt Scheirer 2018-12-11 20:30:05 UTC

I don't think this is either build or packaging related. It seems to be a Qt regression in 5.12. Testing with the latest Krita or QtBase causes double frees in TabletEvent and I can sometimes get a null pointer on destruct.

Currently building 5.12.0 + 4.1.6 and dev + master to produce some gdb traces with symbols. Took forever to hack the outdated AUR qt-base-git package into working...

Comment 4 Matt Scheirer 2018-12-11 22:15:11 UTC

Created attachment 116868 [details]
gdb of 4.1.6 and 5.12.0 with symbols

I'm at a loss. Bisecting this trace led me to https://github.com/qt/qtbase/commit/d2e0e416d4444ccf3c208d6770e32ff0fb04b543 as the culprit. But it was merged into 5.11.3 and I never ran into this bug before 5.12.

At the same time I can generate a myriad of null pointers / double frees poking the canvas and it all comes back to that destructor.

Comment 5 Matt Scheirer 2018-12-11 22:33:48 UTC

Looking back at it there were 6 revisions of the 5.11 package in Arch but Qt 5.11 only had two point releases. That would explain why this is new!

I made an upstream Qt bug for this here: https://bugreports.qt.io/browse/QTBUG-72488

Comment 6 Matt Scheirer 2018-12-11 23:06:56 UTC

You can probably close this - its a Qt bug, not a Krita one. For any other Arch users finding this, revert d2e0e416d4444ccf3c208d6770e32ff0fb04b543 in qt5-base 5.12.0 or just go back to 5.11 until its fixed.

Comment 7 Halla Rempt 2018-12-12 08:57:39 UTC

Thanks for making the bug report!

Comment 8 Halla Rempt 2018-12-12 09:02:15 UTC

Oh! It might be interesting to build Krita with the option USE_QT_XCB=TRUE to disable our forked xcb handling. That will use Qt's xcb (which will cause bugs, like the cursor hanging as in https://bugs.kde.org/show_bug.cgi?id=390642)

Comment 9 Halla Rempt 2018-12-12 12:07:01 UTC

Looks like the problem is that QEvent has a pointer member variable but no copy constructor. The base class qcoreevent has a copy constructor. Krita copies tablet events to put into a motion compressor thing. The pointer member doesn't get copied, there are two tabletevents that own it, both try to delete it.

Work around QTBUG-72488

Qt 5.12 now deletes a void pointer member variable of QTabletEvent.
QTableEvent doesn't implement a copy constructor for QTabletEvent,
but Krita does copy events when compressing move events. Both
the original and the copy try to delete the pointer, and poof.

This is strictly a workaround, only valid for Qt 5.12 and should
be removed if this bug is fixed in Qt 5.12.1 or later.
