The issue I have with LibreOffice isn’t that bad. It’s not a CPU hog, it’s just slow (e.g. moving from cell-to-cell or entering a value takes ~200-300 ms, which is enough lag to make it annoying and difficult to be productive in).
I’m using kernel 5.15.52-1.fc32.
I don’t make any modifications like this. My OS is essentially stock, which is why all of these issues are so confusing. I recently discovered that fedora-34 was at EOL, so I’m trying fedora-36 to see if this will help solve some of these issues. I think many of the sudden qube shutdowns may be networking-related.
