Hi everyone šŸ‘‹ ## Problem When dragging a card it doesnā€™t follow the pointer and keeps lagging behind. Iā€™m not making any heavy calculations or triggering any actions while the the card is being dragged. The only workflow linked to the Kanban is triggered based `On item moved` ## Video > **[2025-09-08 16-44-09.mp4](https://drive.google.com/file/d/16NCXG4f5YA2ruvKiWAkFukrVvVh555Qv/view)** > > Google Drive file. Appreciate your help. ---

@mossab hi, have you tried to clear the logs section inside the editor? If there are a lot of records everything starts to slow down in preview mode. So if your project big enough you need to clear the logs pretty often. ---

Hi @Batik_Okazov, thanks for the suggestion. Yeah Iā€™ve tried that and it didnā€™t make any difference. The project is still in a very early development stage so I donā€™t think it has something WeWeb dashboard canā€™t handle. ---

Got it. What exactly is happening when you trigger OnItemMoved? Can you show the workflow? ---

Sure. I donā€™t think the performance issue has anything to do with this workflow because its actions are only triggered after releasing the card. ![image](https://us1.discourse-cdn.com/flex016/uploads/weweb/original/2X/e/e45fd4f8ef374395140b30cde1863bbe7b830cb1.png) ---

Couldnā€™t post multiple images in one reply, here are some extra details ![image](https://us1.discourse-cdn.com/flex016/uploads/weweb/original/2X/d/d7b8ef3918a742106d8d96af02233ec44f444546.png) I can confirm that while dragging the card, the only thing that gets logged is ā€œ_Setting value for isDrragging_ā€ so no crazy processing or actions are being triggered. ---

Thatā€™s strange indeed. Donā€™t have any other guesses. But the behavior on the video really looks like some heavy process going on. ---

Thanks for trying to help on this one @Batik_Okazov šŸ™ Guess I have to file a bug report for the Weweb team to look into. ---

not at all. Let me know if you find out the reason. Iā€™m curious ---

Hi @Batik_Okazov, Wewebā€™s team mentioned that itā€™s working fine on their end. Iā€™ve asked another developer friend to test it out, no issues on his end too. Maybe it has to do with my setup (Iā€™m using Vivaldi `7.1.3570.47` on Linux). Iā€™m fine with bad dev experience as long at it wonā€™t affect the app users in production šŸ˜…. ---

Oh, so thatā€™s how it is šŸ™‚ I use Vivaldi too, but on Windows. Didnā€™t experience anything like that.
