GIMP is laggy all of the sudden

Software
1

I’m not sure what happened, but as far as I know, nothing did. However GIMP is no longer quick, snappy and responsive as it has been for years now. Moving control points on a curve adjustment lags and drags, snaps around and is generally imprecise. As is zooming in and out on the image. As is most everything in the program.

I’ve tried both the stable version and the development version, both are slow and sluggish.

I’m not sure what to do and where to look, but the difference is so big and noticeable that I’m certains it’s not just me imagining things.

Any ideas?

Start by telling us your OS, the gimp version, what updates have happened recently, and other relevant technical information.

The GIMP versions are 2.10.32-2 and the latest git version, currently 2.99.14 commit a0811ff

As far as what updates have happened recently… well… all of them. I use Arch so it updates several times a day, most of the times.
