Summary: KDENLIVE application is Suspended by MS Windows when
opening a project with lots of sequences
Classification: Applications
Product: kdenlive
Version: 24.02.0
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: User Interface
Assignee: j...@kdenlive.org

Target Milestone: ---
KDENLIVE application is Suspended by MS Windows when opening a project with
lots of sequences
SUMMARY
When opening a project with lots of open sequences, KDENLIVE application is
Suspended by MS Windows during the process of opening each sequence.
STEPS TO REPRODUCE
1. Create a project with 100 sequences that are all open
2. Save the project and close it
3. Open Windows Task Manager to the processes tab
3. Open the project and KDENLIVE will start to open each of the sequences
4. Eventually KDENLIVE will stall and Task Manager will show KDENLIVE as being
suspended
5. The only thing you can do now is kill the process
OBSERVED RESULT
* I opened my project file in a text editor and found the property
"kdenlive:docproperties.opensequences".
* I had 112 entries here and it would repeatedly stall on the 96th entry
* If I cleared the contents of the opensequences property and saved the file I
was successfully able to open it in KDENLIVE as it's not loading each sequence
on startup.
* As a test I removed (using the text editor) the first 63 sequences which left
me with the last 49. KDENLIVE successfully opened the project, concluding that
it was not stalling on a corrupted sequence.
* During project opening, the computer was only using 25% CPU and 14GB ram (50
free)
EXPECTED RESULT
* Perhaps KDENLIVE needs some mechanism from preventing it from becoming
suspended by Windows during this phase of opening sequences.
* A user who does not know they can edit their file in a text editor and remove
the values in the opensequences property essentially ends up with a bricked
project file.
SOFTWARE/OS VERSIONS
Windows: 10 19045.4170
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2 (built against 6.6.2)
ADDITIONAL INFORMATION
* I admit that having 112 sequences open is excessive and I now close a
sequence if I am finished editing it
