Problem Description

When I run Python code interactively via the Spyder IDE, it is extremely slow. This is particularly the case when I split the screen horizontally. I've checked that I'm not running any heavy processes in the background. It happens even if I run simple programs with almost no data.

What steps reproduce the problem?

Split the screen horizontally
Run any program interactively for more than 5 minutes

Hey @muhlbach, thanks for reporting. The only known workaround to make Spyder work in Big Sur is to download our DMG installer and then connect it to your conda environments by following our FAQ here.

All users that tried this have reported it solves the lags for them. Please try it and let us know if it works for you.

ccordoba12 commented 3 years ago

I also want to emphasize that this is not our fault but Anaconda's because they haven't updated their Qt/PyQt packages (the graphical toolkit Spyder is built on) in a long time, and the current version doesn't support Big Sur.

muhlbach commented 3 years ago

Hey @ccordoba12! Thank you for the prompt reply (and thank you for a great IDE, love Spyder)!

Okay, fair enough. I will try the DMG installer then. What happens if I then run something like conda update --all with Spyder being installed via the dmg?

Also, I don't believe I had this problem for earlier version of Spyder. Do you think it would work for me to downgrade Spyder to 4.X?

ccordoba12 commented 3 years ago

and thank you for a great IDE, love Spyder

Glad to hear that!

What happens if I then run something like conda update --all with Spyder being installed via the dmg?

There won't be any problems. You can safely keep using conda along our DMG installer. That's because our installer comes with a separate Python version, so it doesn't interfere with Anaconda.

Also, I don't believe I had this problem for earlier version of Spyder. Do you think it would work for me to downgrade Spyder to 4.X?

Unfortunately, that won't change anything. This problem is not related to Spyder but to Qt, so all our versions are affected by it.

ccordoba12 commented 3 years ago

I'm going to close this issue because I think there's no more we can do for you.
