20150116 08:55:22 <eclesia> hi
20150116 09:01:30 <monsieur_max> hi eclesia
20150116 09:08:40 <monsieur_max> my current work, finding what did i do wrong to have screen tearing in a newt window even using setSwapInterval to 1
20150116 09:09:13 <eclesia> the gods are not here, you will have to way ^^
20150116 09:09:39 <monsieur_max> i'm a strong man who don't need no god ! :)
20150116 09:11:09 <monsieur_max> eclesia: ever faced this issue ?
20150116 09:11:31 <eclesia> what is 'tearing' ?
20150116 09:12:06 <monsieur_max> screen being redrawn even if the previous one has not been finished
20150116 09:12:36 <monsieur_max> it's a very visual problem
20150116 09:14:20 <monsieur_max> eclesia: example : https://www.youtube.com/watch?v=7juA4v9Z8EM#t=254
20150116 09:15:22 <eclesia> hm nope, never seen this
20150116 09:17:05 <zubzub> with wayland, no more tears ;)
20150116 09:17:22 <zubzub> unless the client misbehaves, tearing is impossible
20150116 09:19:50 <monsieur_max> zubzub: unfortunately, i can't expect wayland to fix my issue here :)
20150116 09:20:45 <zubzub> you can always try :p
20150116 09:20:47 <zubzub> j/k

20150116 14:51:34 <monsieur_max> answer to my tearing issue, it my be because i'm not using double buffering for my FBOs... I know what I'll to code this week end :)
20150116 15:36:10 <zubzub> yes if you don't want tearing you must use double buffering
20150116 15:42:20 <monsieur_max> :) i'm no expert and did not realized i needed tha on my FBOs too, makes sense

20150116 16:24:46 <rmk0> you ... don't need it on FBOs
20150116 16:24:55 <rmk0> only the screen/window!
20150116 16:26:29 <rmk0> not sure what having double buffering on an FBO would even mean
20150116 16:28:31 <rmk0> tearing is usually down to a lack of vsync
20150116 16:32:17 <zubzub> *the compositor is not vsync'ing
20150116 16:32:35 <zubzub> or the app is giving 'busy' buffers to the compositor
20150116 16:33:03 <zubzub> on linux with X you can not vsync, unless you have an opengl compositor (eg ubuntu)
20150116 16:33:28 <zubzub> (the app can still vsync tough)
20150116 16:33:41 <zubzub> but X will fuck it up for you iirc
20150116 16:42:10 <rmk0> i seem to get vsync (or at least a lack of tearing and a fixed 75fps framerate) here
20150116 16:42:16 <rmk0> this is on X, without a compositor
20150116 16:42:28 <rmk0> i can turn it off and get tearing
20150116 16:44:06 <rmk0> i do remember when it was practically impossible to get vsync
