Text input is very slow
For some unknown reason the text input got super sluggish recently in Thonny. It takes a while after the keypress is recognized.
It can also happen that while scrolling with arrow keys the text cursor is so slow that i have to wait several seconds before i can start typing again. It worked well before and i don't really know what to do about it.
I tried it on a different ubuntu machine and it works fine. But in other editors on my Manajaro machine i don't see such a behavior so it's something about Thonny.
Before testing i deleted the .config/Thonny folder, thus a fresh default config was used. Furthermore i restarted my computer and closed all other programs to make sure it is not related to something else.
Thonny 5.0.0b1-dev (latest/2024-07-12 git version) Manjaro Linux Python 3.12.4 Tk 8.6.14
Can you try again an older version, which worked well? It would be a great help if you could find out the specific commit, which introduced this problem (perhaps with git bisect).
Without this I don't have any ideas where to look, because I haven't touched Thonny's editor for a while.
I went back as far as 3.3.0b7-dev and it was still present. So it seems to be only indirectly connected to Thonny.
It seems to something about a blocking IO operations since i notice hard drive activity when typing or moving the mouse cursor.
Thanks for the investigation?
Some people have experienced decline in performance when upgrading their Raspberry Pi-s to Bookworm (#3036). Perhapse there is something similar going on with Manjaro.
Can you please check, whether Python's IDLE (which uses the same GUI toolkit, as Thonny) has same problems?
Indeed IDLE and also MrPython (which is based on IDLE) show this sluggish key input behavior.
