I have found that when using applications like clementine that uses inotify setting it to 10 000 does not help, it needs to be set to 1048576 when the library is 100 000+. This is the only part in the wiki that mentions this value. So I think we need to add a mention here for large collections or have a page that explains inotify a little more.

Screen tearing in nvidia tip
The suggested method have a big impact on many games. It's better to first try enabling the triple buffer, as suggested here: https://wiki.archlinux.org/index.php/NVIDIA/Troubleshooting#Avoid_screen_tearing
Maybe it would be a good thing to remove the USLEEP suggestion and link to that page instead.
- Agreed on the linking part. However, "enabling" triple buffering is not better, see the discussion page of the linked article.

- I found a better solution for USLEEP which is also Plasma/KWin specific.

- I tried this new tip, as a startup script, but I had some issues. The windows of the applications loaded from the previous session pops out of the splash screen. I suppose that happens when kwin is restarted. Furthermore, my desktop appears completely black and without icons. I need to kill and restart plasmashell to restore it. In my personal experience I found the full composition pipeline + triple buffer trick a better solution for the tearing issue and with a imperceptible impact on performances (i7 4790 and nvidia GTX 1060 here).

- Have you tried delaying the scrip by a few seconds via sleep? I did a dozen restarts or so without issues. However, I'm not restoring previous sessions.
- Aufkrawall (talk) 10:17, 27 October 2017 (UTC)
- Adding a 5 seconds sleep in the script solves the issues. Strangeley, I found that with this and even without any trick to fix tearing in kwin, the unity engine game I used to test (Tacoma) have some stutter in the more complex scenes. It looks like the other tip (full pl + triple buffer) somehow improves the smoothness, as opposed to what I had read. I can't explain that.

Magic Trick (~/.compose-cache) - does it still work?
It seems information of
~/.compose-cache has been lost?
After a bit of testing, it still seems to work just fine:
ls -lh ~/.compose-cache
-rw------- 1 archie archie 29K 5 mrt 19:27 l4_030_20fca6bc_0e7768ba -rw------- 1 archie archie 418K 5 mrt 17:23 l4_030_313cb605_00280cc0
- Is there any upstream link for this trick? We need to show user this low level trick is actually useful. -- Fengchao (talk) 08:42, 22 November 2019 (UTC)
- No upstream link, but I'm using the following as reference:
