Qwen image editing's dotted-pattern problem: 50 steps needed, QIE sampler worst offender
Druck_Triver · reddit · 2026-09-21
A Reddit user documents a known issue across Qwen image editing models: a visible dotted pattern in outputs.
Key points:
- On Qwen 2512, the author found some images needed 50 sampling steps instead of the usual 20 to look right;
- QIE was the worst offender;
- On 2509, using the "paint green areas then inpaint" trick (borrowed from Kontext) took 7 minutes only to produce a filled area covered in large ugly dots;
- The author still likes Qwen 2.1's editing and finds the dots less prominent in that version.
A practical sampler-and-steps pitfall reference for anyone doing image editing with Qwen.
