Created attachment 125663 [details] Backtrace of the crash SUMMARY I don't know the exact steps to reproduce this, but since I updated to KDevelop 5.5.0, I get a crash quite frequently when I highlight some code, for example when you want to delete a block of text. Unfortunately the backtrace doesn't seem to be helpful. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora 31 (available in About System) KDE Plasma Version: 5.17.5 KDE Frameworks Version: 5.66 Qt Version: 5.13.2

Jan, if you can also reproduce this issue, please - would you be willing to look at the (old and crude) code in try to figure out how we can fix it on a hidpi system (assuming you are also running into this issue due to hidpi problems)
