Description Dāvis 2026-01-15 16:37:26 UTC 
SUMMARY

When I copy text from Firefox that's huge (many MiBs) and paste it in KWrite then whole application freezes for minutes. It's taking so long that I never have seen it completing as I kill it when I lose patience :D

STEPS TO REPRODUCE
1. Copy MBs of text from Firefox
2.  Paste in KWrite

OBSERVED RESULT

KWrite freezes, can only be force killed.

EXPECTED RESULT

To not freeze and paste normally.
