Description Akseli Lahtinen 2025-08-06 14:01:08 UTC 
SUMMARY

If user has only one item on desktop, and it's in top left position (so that positioner code thinks its in 0x0 coords), the item will not show up. Gammaray shows that the delegates are not even being created.

STEPS TO REPRODUCE
1. Make sure desktop folder is empty and sorting is set to "unchanged"
2. Add one item to desktop top-left corner by right clicking

OBSERVED RESULT
No icon appears

EXPECTED RESULT
Icon should show up
