05:08 <freemangordon> uvos: Maybe it renders fonts, dunno

05:09 <freemangordon> but it seems it is not the reason for the massive fps drop when hildon runs

05:10 <freemangordon> IIUC it is that hildon must copy every offscreen buffer frame, but maybe it does not track the damage correctly

05:11 <freemangordon> and copies the full offscreen buffer every time

05:30 <freemangordon> hmm, even if I stop h-d, scrolling in abook (for example) is still slow

05:31 <freemangordon> could it be that gtk is doing bad things?

08:05 <uvos> freemangordon: i think gtk2 is just slow at scrolling beacuse it renders eatch frame

08:06 <uvos> qt is 1 hw accelerated and 2 in sw just blits the viewport up a bit and renders the bottom sliver

08:06 <uvos> i doubt this is related to comp.

08:09 <uvos> i mean comp. is slow on x also because of the extra ipc, idk how mutch this adds, but in x the application usualy renders bits to a buffer and hands that to x to render as a pixmap onto its window, where x then maybe also dose some of its own rendering and the buffer is handed to the compositor to compose onto the display

08:10 <uvos> that this is inefficant and makes x a sorta useless step is why wayland got started

08:11 <uvos> maybe instead of trying to make this faster i would be more worth wile to just run in uncomposited mode most of the time

08:11 <uvos> except while displaying tasknav or a notification banner

08:11 <uvos> hildon dosent need to be composited at all

08:11 <uvos> and it almost works

08:12 <uvos> if you force disable comp. on a non-fullscreen window

08:12 <uvos> hildon will switch back as soon as one of those things are needed

08:14 <uvos> the only problem is that the window title bar that hildon renders is missing, im not sure why that, probubbly because its not a real window but is just clutter geometry thats added during compositing, is but there is no reason that could not be a regular x window above the application window.

08:16 <uvos> if we change that (not sure how mutch work in hildon) we could just allways be whithout compositing while there is a application window on top

08:16 <uvos> that saves a huge amount of ram too

08:23 <Wizzup> switching would be much slower though

08:34 <uvos> its ok

08:34 <uvos> really

08:34 <uvos> (try it)

08:35 <uvos> but yes switching causes some extra delay

20:36 <norayr> > Wizzup: plz RT https://twitter.com/buZztiaan/status/1577677393925472260 ;)

20:36 <norayr> amazing

20:36 <norayr> > 2022-10-05 07:09 (GMT+04:00)

20:40 <buZz> heh, yeah!

20:41 <buZz> runs really well, i need to figure out debian packaging though so i can push it to extras

20:41 <buZz> and also do that ps1 emulator

20:42 <norayr> not that hard apparently, look at our packages in extras and ask here questions. the important thing is that it builds.

20:46 <buZz> yeah i just need to 'mkdir build; cd build; cmake .. -Ddisablealltests; make' and its done

20:47 <buZz> so some project like that
