Qwt 6.2 - problems with high dpi scaling

[Uwe]

Which Qt version ?
Do you also see the problem when using https://sourceforge.net/p/qwt/git/ci/qwt-6.2/tree/ ?

The Qt version we are using is 5.14.0.

I am not sure about your second question. The problem occurs with qwt 6.2.0, qwt 6.1.4 worked fine (we can exactly define the commit when the problem showed up and that commit was the upgrade from qwt 6.1.4 to qwt 6.2). Does your link lead to an advanced version of qwt 6.2? If yes, I will try it.

Does your link lead to an advanced version of qwt 6.2?

This is the 6.2 branch, with all bugfixes that have been reported so far against 6.2.0. The next minor release ( = 6.2.1 ) will be made of it.
It does not include changes that break binary compatibility - those exclusively go to the development branch ( https://sourceforge.net/p/qwt/git/ci/develop/tree/ )

Thank you for the information. I tried with the binary compatible version containing the bugfixes and the bug is gone.

So my next question is do you already have an ETA for the 6.2.1? Or can you recommend using the bugfix version as it is now?

[Uwe]

A bugfix branch should always be better than the latest corresponding release. According Qwt 6.2.1: guess it is time to publish what has been fixed over the last 2 years.
Also note, that the development branch should also have no bugs. However its API is not stable yet.

Thank you for the information.
