[RFE] Ubuntu ppa about kwin-lowlatency

[maxiberta]

Fyi, I've recently set up a PPA with daily kwin builds based on this simple Launchpad recipe, which auto-builds packages by merging this repo's code with kubuntu's build instructions:

https://launchpad.net/~maxiberta/+archive/ubuntu/kwin-lowlatency

Note it's my first PPA and things might break (but it hasn't failed a single build so far, and it did pretty well with the kwin 5.17.2 -> 5.17.3 bump :-) ).

Hmm, meanwhile (under KDE Neon / Ubuntu based) I made a dirty "make install" over my existing installation (as checkinstall failed to build the deb). I guess that's not advised at all ;-)

Difference with stock kwin is stellar on my 144 Hz display, everything is butter smooth. In 60 Hz I'm not sure, seems slower in some cases (have to double check).

(I just noticed something strange in a game - Two Point Hospital -- where it would scroll without my wanting it until I alt-tabbed -- would happen several times in a session. I'm pretty sure it didn't occur with stock kwin & composition suspension)

I have considered this in my mind before, but began to doubt because it may require backporting, and setting up a few Ubuntu virtual machines (and I'm running low on disk space).

I will begin working on this as soon as I get an external hard drive to move all my recordings into and hence free some disk space.

If you make a PPA you can use Launchpad's builders, just create a recipe. E.g.: https://code.launchpad.net/~stk/+recipe/stk-1.0

Yup, I could, but I need to test that it works as well.

You can always support only the latest kubuntu to minize backporting efforts.

Go for it then. Just take the package definition of KWin on Kubuntu and change a few lines. I did this for openSUSE. Didn't take more than a few minutes.

I've noticed that too from time to time, but i thought it was just wine/proton being funny. I'd make a bug report on it if i were you.

Yep, I'm almost sure it doesn't happen with regular kwin (and when disabling compositing it doesn't happen). Thing is I don't know how to have both kwin versions on my single Neon installation. Also, I would maybe have to offer a key of the game to the developer for him to check ;)

Maybe it's time for me to read some KDE devs/triagers wiki...

You can run kwin-lowlatency from the build directory without installing it. There are instructions for that in the hacking.md file
