With the Qt 6.10 update I've started noticing a strange behavior with the Terminus font, which is the font I use in the terminal (QTerminal), in the text editor (Featherpad) and in the process manager (qps). When scrolling or enlarging, the window becomes unresponsive, and this is happening only when the Terminus font is used in Qt programs. This wasn't happening with the previous Qt version, that's why I'm thinking the problem is in Qt 6.10.

Sorry if I can't provide more information, but I'm not expert here. I remember something similar also happened when upgrading Qt from 6.3 to 6.4 (if I remember correctly). That was fixed with an update some days after.
