Bug ID: 470174
Summary: 40 Characters Annotation consuming 20MB
Classification: Applications
Product: okular
Version: 23.04.1
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: general

Created attachment 159208

File with one comment with text "a" - original size ~80kb now 2MB!
I commented a file with a few characters. Initially the file had ~ 80KB. With
the annotations ~20MB and Okular had an excessive CPU consumption (100% of a
core - should be 1 Thread that behaves strange) The CPU consumtion starts when
scrolling. With 12 comments my file was lagging on scroll. When comment is
deleted, file keeps memory consumption.
Tried it with some other files. About 4MB for one comment with a few characters
like "aspofksdfjdsafjfsadpfg"!
EXPECTED RESULT
Annotations to consume < 10KB for text only per comment and use 0.01% of CPU.
The file should have the original size after deletion of comments.
