22:45 <Wizzup> Things have much improved since I updated mesa, which is great, but compositing seems buggy somehow

22:45 <Wizzup> (the device is the 'pinephone')

22:45 <Wizzup> I have a few (relatively) simple cases when I can reproduce bugs where the screen is not correctly redrawn, and in other cases some textures from windows below the current window seem to show in the current window

22:45 <Wizzup> It doesn't seem to be a bug in modesetting or X, since it works on other devices with other drivers, and also with llvmpipe on the pinephone

22:45 <Wizzup> if I disable compositing for a window and then put something on top of it, the problem disappears

22:45 <Wizzup> the window manager in this case is hildon-desktop (from maemo)

22:45 <Wizzup> so I guess my question is, what can I do to file a useful bug report?

22:49 <enunes> Wizzup: well, if you can put some effort into it ideally you could provide an apitrace of the application (in this case the compositor?) reproducing the issue

22:50 <Wizzup> ok, I can do that

23:01 <Wizzup> enunes: hm... this is particualrly weird, but it looks like I cannot reproduce the problem when running under apitrace

23:03 <enunes> Wizzup: is it the same environment that the compositor runs otherwise other than apitrace?

23:04 <Wizzup> I believe it is the same, yes

23:06 <Wizzup> I suppose that could point to some timing issues, but it does look like one of the issues I am seeing remains

23:06 <enunes> like if you run the compositor manually it reproduces, but then also manually with apitrace it doesnt?

23:07 <enunes> just to make sure you are not comparing manually vs run by a login manager or something

23:07 <Wizzup> enunes: yes, that is right, both spawned from the same login shell over ssh

23:08 <enunes> well if you can confirm at least one of the issues does reproduce, thats a start

23:09 <Wizzup> yeah - I'll come back tomorrow with some (hopefully) useful traces

23:12 <enunes> timing issues havent been much of a thing so I am a bit skeptical of that

23:15 <Wizzup> I see a lot of glitching (old pixmaps/data being rendered when it shouldn't), also in firefox, but now when I run hildon-desktop with apitrace, it's fine. (slow, but fine)

23:16 <Wizzup> I'll also try to make a video in addition to the traces tomorrow (it's getting late here)
