Picom: Using blur theme with picom on an old computer

[Joe23232]

If on an old computer, I used awesome Window Manager and I use picom as my compositor, and I decided to use a slight blur theme to the background of the windows, would it cause a huge overhead and cause high CPU usage when moving the windows around?

I heard from a friend that they used compton and they had this issue, so with picom (as it is a fork of compton) would the same issue occur?

Why don't you try it and see if it's a real issue instead of opening an issue that you are not sure even exists in picom?

@Finxert Yeah I haven't even installed Linux yet. But yeah now I know that a lot of people on Reddit are complaining about performance issues when using picom when using the blur theme which is a bit unfortunate :/

[Finxert]

afaik the dual kawase filter picom uses is more efficient at higher blur strengths and tryone-comptons single kawase is more efficient at lower blur strengths.

I don't think your machine would have performance issues with either of these unless it's really ancient. tbh I realized lower blur settings look bad and it's better to run opacity alone, so I don't think it's too dramatic of an issue.

Still though I don't think this place is appropriate to open "issues" like theses, especially when you don't even have a linux system. I'd ask this on some forum rather than in a place where real bugs are meant to be reported.
