Screencast of the issue

I can reproduce on Debian testing in a Plasma Wayland session, s. attached screencast attachment 183322 [details]:

1) open attached sample doc attachment 183321 [details]
2) select cell A1
3) click the "Clone Formatting" toolbar icon
4) click cell A2

Actual result:

Cell A3 gets yellow background.

Expected result:

Cell A2 should get yellow background.

It works as expected when explicitly choosing Qt's X11 platform plugin instead (environment variable QT_QPA_PLATFORM=xcb).

What's also noticeable is that the cursor does not change to one showing the "clone formatting" icon when using the Wayland backend.
This may be a LO issue, or one in the Qt library.

I can no longer reproduce on a current Debian testing with

Version: 7.6.0.0.alpha0+ (X86_64) / LibreOffice Community

And I cannot even reproduce with the same version I was using back then, now from the bibisect repository:

Version: 7.5.0.0.alpha0+ (X86_64) / LibreOffice Community

The latter shows no cursor any more, which was fixed in the context of tdf#153333, and that was probably also what this comment was talking about:

It looks like cursor handling in KWin or Qt has changed, and this has fixed the issue described here.

-> Closing as WORKSFORME (could also use NOTOURBUG due to the above observations)

@Robby: Could you please retest with latest KDE and Qt versions as well and reopen this issue if you still see the problem then?

Version of packages on my current Debian testing where it works as expected:

kwin-wayland                           4:5.26.90-1
libqt5waylandclient5:amd64 5.15.8-2

The offset during clone formating may be solved.
However, it is hard to evaluate, because the cursor is invisible during using the tool.

This is a Qt bug, but there's a solution in LO that avoids the issue, s. tdf#153333. Can you please retest with a version that includes the corresponding change?

There are e.g. daily development builds available at [1]. [2] describes how to install them in parallel to an existing LO version. (Alternatively, you can wait until 7.5.2 is released.)

[2] https://wiki.documentfoundation.org/Installing_in_parallel/Linux

waited and everything is fine now with 7.5.2

Great, thanks for confirming.
