Description Callegar 2023-01-01 13:50:44 UTC
Description:
You have a polygon line and you want to split the line at some point. So, you activate "Points (F8)" and you try to select the point where you want to split the line.

This is all good with the GTK4 VCL. As you get close to a point in the polygon line, the cursor changes into an arrow with a little square on one side. You place the arrow head on the point you want to select and click.

Now try to do the same with the KDE VCL. As soon as you get close to the point you want to select, the cursor turns into a cicle with four little arrows around. This is the cursor that is generally meant to /move/ things, not to select them and is already wrong. But this is not the end of the story. When you try to pick the point, you find that the cursor starts jumping around as it does not want to go on top of the point you want to pick.

Just verified that this only happens in Wayland. X11 is fine.
Comment 2 Callegar 2023-01-01 13:59:22 UTC
So I guess it may not be a LibO bug after all, but a bug in QT5, Wayland, KWin or whatever among the tons of little things that are half broken in Wayland. Consider closing if the bug is elsewhere.
Comment 3 Stéphane Guillou (stragu) 2023-01-02 17:22:08 UTC
Can't reproduce with:

Version: 7.5.0.1 (X86_64) / LibreOffice Community
Build ID: 77cd3d7ad4445740a0c6cf977992dafd8ebad8df
CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: kf5 (cairo+xcb)
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: threaded

However, with Wayland, in my case, the cursor disappears entirely but it is still possible to select and drag the point (no jumping around).

Version: 7.5.0.1 (X86_64) / LibreOffice Community
Build ID: 77cd3d7ad4445740a0c6cf977992dafd8ebad8df
CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: kf5 (cairo+wayland)
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: threaded

Sounds very similar to what is described in bug 147450.
Mention of jumping pointer on Wayland also in bug 150321.

Can you please copy-paste here the info from Help > About LibreOffice?
