Created attachment 150173 [details] Picture of GammaRay showing the continuous instanciation of QMimeData & DataControlSource classes SUMMARY After boot, Plasmashell used a very high amount of CPU power and RAM. It seems to be related to QMimeData (Drag & Drop) and DataControlSource as there was a huge amount of these objects (at the end ~ 8 million). This information was shown by GammaRay (screenshot attached). STEPS TO REPRODUCE Unknown. OBSERVED RESULT High CPU and RAM usage until Plasmashell was killed by the system. EXPECTED RESULT No high CPU and memory usage. SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 5.25.1 KDE Frameworks Version: 5.95.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION Probably related to bugs 454590 & 455625, but now in a newer version.
