Description Claudius Ellsel 2020-08-24 20:41:09 UTC
SUMMARY
When dragging a file, the position of the mouse cursor seems to be offset. I cannot drag it all to the left and I can drag it off screen on the right. It also affects the position where I point at in the panel (dragging to an app in the task manager for example).

It might only be some visual thing that the mouse cursor is displayed at the wrong place or something like that.

STEPS TO REPRODUCE
1. Open dolphin
2. Drag a file from there
3. Try to drag it all to the left (or to the right)

OBSERVED RESULT
The cursor is (or seems to be) offset.

EXPECTED RESULT
No offset

I can't reproduce this issue of the task manager highlight being wrong on X11. Does it happen for you on X11, or just Wayland? Thanks for using and Testing Wayland, BTW :)

I haven't tested on X11, yet. I will update shortly with the result.

Plasma on Wayland is the only combination that gets me a decent mouse wheel scrolling speed on Linux (the problem seems to be not existing when using a touchpad), thus I am using that :)

Note the highlight on Firefox while the item is dragged on Gwenview.

Does not happen on X11, just Wayland, so setting appropriate keyword.

Not related: Note that https://bugs.kde.org/show_bug.cgi?id=425258 (Screenshot https://bugsfiles.kde.org/attachment.cgi?id=130822) might be only there on Wayland. I think I cannot reproduce, but the offset of the mouse cursor from the dragged image shown in the screenshot from that bug report seems to be pretty extreme. For me the cursor slightly touches the dragged item and does not sit about 3/4 of the items height above it.

I have written about a very similar issue in dolphin under

Cannot reproduce on a git master Plasma Wayland session, so it may have been fixed recently. Can you try again? Thanks!
