    Description

      Very similar to https://bugreports.qt.io/browse/QTBUG-45959 and https://bugs.kde.org/show_bug.cgi?id=347237

      except Nvidia driver, because in this case OS runs inside a virtual machine VMware Workstation 15 with vmware-video (vmwgfx) driver.

      A bug appeared immediately after upgrading QT from 5.12.1 to 5.12.2 in Manjaro Linux KDE edition.

      The progress indicator/spinner which appears in the panel when opening applications or copying files spins as fast as it can and thus causes 100% CPU usage on one core by process plasmashell.

      Steps to reproduce:

      1. Run Manjaro KDE inside VMware Player or VMware Workstation

      2. Copy a large file (or just start copying the file and pause it) and watch the spinner in tray as well as plasmashell's CPU usage
