Perfomance Issues on 1.14

[Paranoid]

Aloha,

using amd64 on debian sid and just realized that my system has low performance now. It seems to be the interaction or communication with the xserver.

• 1.12 uses 6.6% of cpu, xorg is around 3.0%

• 1.14 user 4.5% of cpu but xorg is now flotaing between 50% and 90%

Some system information.

grep LoadModule $HOME/.local/share/xorg/Xorg.0.log

You could try rebuilding with the options -DARCH=native -DENABLE_LTO=yes, though I don't know how much that would help given Wesnoth itself isn't the one taking up most of your CPU. You could also try disabling various options in Preferences > Display, animated water in particular.

I've done the rebuild but there are no changes in performance.
I've also changed / disabled some graphic options but that didn't help. And as far as i understand the problem this is expected. Bad performance starts at launchtime. The starting screen - no actions and no animation - triggers this behavior too.

As far as i understand changing preferences will have effects on the wesnoth process only. But wesnoth itself is performing fine.

I'm not sure what else to tell you then, sorry. I have Mint 18.3, and don't experience any unusually high CPU usage.
