Description Raghavendra kamath 2022-09-22 07:34:42 UTC

SUMMARY
If a psd file contains fill layer either saved from photoshop or from krita itself. krita crashes or hangs when opening that file. if you reopen krita and if this file is in the recent document list, krita will hang or crash on startup. 


STEPS TO REPRODUCE
1. Create a new document.
2. Add a new fill layer with any colour 
3. Save the document as PSD and now close krita and open that PSD.

OBSERVED RESULT
Krita hangs or crashes.

EXPECTED RESULT
File should be opened normally

This happens on both windows and linux. This was first reported on krita-artists here - https://krita-artists.org/t/krita-5-1-1-crash-on-startup-reinstallation-does-not-work/48185/1

Comment 1 Halla Rempt 2022-09-22 08:10:53 UTC

I cannot reproduce a crash in current master or with the 5.1.1 appimage: the image from the original thread loads normally.

Comment 2 Halla Rempt 2022-09-22 08:15:45 UTC

Ah, no, I'm wrong. Krita can load the image fine, but the kimageformats framework which we use to load the thumbnails seems to crash.

Comment 3 Halla Rempt 2022-09-22 08:28:43 UTC

Okay, this is due to

Use Krita's engine to load previews for PSD files

It makes loading of preview for the complex file from bug 444844
reduce from 300 sec to 40 sec.

BUG:456907

Because PSD files can contain references to resources, and the thumbnails are generated in a background thread, not the gui thread, and resources can only be accessed from the gui thread.

Revert "Use Krita's engine to load previews for PSD files"

This reverts commit 48ca610ae89be95eb1db477379e54b37ab478ec2.

This made Krita try to access resources in a background thread,
which is not possible.
