ADDITIONAL INFORMATION
Comment 1 Nate Graham 2025-12-12 16:30:13 UTC
I can't reproduce this issue on current git master. The dragged item sticks to the pointer when zoomed in.
Comment 2 hernan1342 2025-12-12 17:29:09 UTC
Just an FYI: updated the Frameworks to 6.21.0 and the problem persists.
Comment 3 Vlad Zahorodnii 2025-12-15 08:32:59 UTC
Please share your zoom effect settings.

Sorry for the delay. I'm using the push mode, otherwise default settings.
Just noticed by testing the other modes that the "proportional" doesn't show the problem, while the "push" and "centered" show that behavior.
Comment 5 hernan1342 2025-12-26 05:31:49 UTC
Just noticed that the same thing happens when, while zoomed, shaking the cursor, then two cursors are shown, the regular size and the bigger one (because of the shake cursor effect)
Again, in "proportional" mode that doesn't happen, but it does in "push" and "centered" modes

I already provided the zoom settings as requested, but here we can see it in the screenshot.
