Yarpscope not working properly on MacOS with multiple coloumns/row

[lrapetti]

Describe the bug When running a yarpscope with multiple rows/coloumns, only one of the plots is shown correctly. The behaviour also seems to be changing if I move the scope between the two screens connected to my laptop (see the following video). (Note that the problem is happening even if no external screen is connected)

To Reproduce Here are the configuration files that I have tested in the video below:

• multiple columns: yarpscope_test.xml.txt
• multiple rows: yarpscope_test_2.xml.txt

I run then without the source data being published, but I still would expect to see the plots (with data=0).

$ yarpscope --xml yarpscope_test.xml

Expected behavior I would expect to visualize the two plots, as I see it working on windows:

• MacOS
• Windows

Configuration:

• OS: MacOS 11.3.1
• yarp version: 3.4.6
• compiler: clang version 12.0.5

Additional context I think a similar problem was experienced in Ubuntu. @kouroshD can you confirm it?

Yes, that's correct.

This is probably a bug in Qt5. What version are you using?
