Steps to reproduce the issue:
- connect three AMD cards and download driver from website.
- three GPU should connect with one monitor each.
- launch Radeon Software and drag between three monitor
- App will be cut in one of the monitor, the attachments are video and picture.
This issue can be observed in QT 5.15, also try the same code base but with QT 5.14 not seeing this issue.
You need AMD's card to launch RadeonSoftware. Also try with one AMD card + 3 NV's card issue still be able to repro.
