SUMMARY In an attempt to reproduce https://bugs.kde.org/show_bug.cgi?id=410163 I got this crash. STEPS TO REPRODUCE 1. Make a file layer 2. Attach a transform mask 3. With transform mask selected, move the file layer. 4. Now select the file layer itself. 5. Move it around a couple of times. OBSERVED RESULT Eventually it will crash. EXPECTED RESULT That the file layer and the mask get moved somehow. I was trying to see if I could reproduce the outine bug, didn't expect a crash at all.

This is one for dmitry. The assert happens here: void prepareClone(KisPaintDeviceSP src) { prepareCloneImpl(src, src->m_d->currentData()); Q_ASSERT(fastBitBltPossible(src)); }
It's possible the assert is just broken when layers have been moved since it does: bool fastBitBltPossibleImpl(Data *srcData) { return x() == srcData->x() && y() == srcData->y() && *colorSpace() == *srcData->colorSpace(); }
The assert is correct, but the entire situation is not :) Moves are usually exclusive, I don't know how it could happen concurrently.

Make sure that fake original() of KisFileLayer has defaultBounds() set Before KisFileLayer loaded its image (or when the image is not available), file layer uses a fake paint device. This paint device should also have proper default bounds set.

Implement KisDefaultBounds::sourceCookie() It is needed for debugging/sanity-check purposes only. It returns an abstract pointer to the source object, where default bounds takes its data from. One can ckeck if the pointer is null or compare two pointers of different default bounds objects.

Git commit 77c57103e7b9c322ddbe189bda1656afed927508 by Dmitry Kazakov. Committed on 20/11/2019 at 11:27. Pushed by dkazakov into branch 'master'. Fix crash when moving a layer under a transformation mask When doing KisPaintDevice::prepareClone(), we should first set new defaultBounds object, and only after that clone the data. The reason for this: switching defaultBounds can change current level-of-detail/frameId, and therefore, switch currentData().
