I get the same bugs as @vkireyeu, namely Geany often freezes when typing or erasing text and freezes when attempting to switch tabs. When typing or erasing text a "CTRL+S" sometimes unfreezes Geany. You can type when it is frozen and the input correctly appears on screen when Geany unfreezes. The "CRTL+S" method does not unfreeze Geany when trying to switch tabs. A "ALT+TAB" to switch to other applications (tried with Chrome and Terminal) solves the freeze every time for both the typing freeze and the tab switching freeze.
I am currently using POP!_os 20.10 and Geany 1.36, no plug-ins are enabled. `echo $XDG_SESSION_TYPE` returns `x11`
