Intel graphics slow off-screen rendering

This issue is fixed in ubuntu, but not fixed in arch: https://bugs.launchpad.net/ubuntu/+sour … bug/999493
I has an Intel HD Graphics 4000 videocard, and this issue is repeated when i'm minimizing any 3D game (Minecraft for example)

Re: Intel graphics slow off-screen rendering

sashok724, those kind of problems tend to be specific to a certain chipset.
Even if you got the exact same hardware as mentioned in that ubuntu bugreport, it's 2 years old and unlikely to be helpful.

please post the output of lspci , dmesg and /var/log/Xorg.0.log .
(dmesg and Xorg.0.log will be large, best put them on a pastebin site)

glxinfo output (it's in mesa-demos package) could also help.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

This issue

*What* issue?

Forget that Ubuntu bug report, it's nonsense, probably confusion over vsync (60hz, sometimes reported as 59hz).

Re: Intel graphics slow off-screen rendering

The only thing that stands out in those logs are these lines :

[ 3999.324519] perf samples too long (2514 > 2500), lowering kernel.perf_event_max_sample_rate to 50100
[10283.298371] perf samples too long (5025 > 4990), lowering kernel.perf_event_max_sample_rate to 25200

I very much doubt they have to do with your lag though.

sashok724, what WM/DE (KDE, Gnome, Openbox, xfce etc) are you using ?

What makes you think your problem has to do with off-screen rendering ?
Please try to describe what happens when you experience this 'lag' .

Re: Intel graphics slow off-screen rendering

KDE, but the same on xfce4

The problem arises, for example, when I minimize Minecraft window (or any other application with OpenGL) or selecting other tab in Google Chrome (previous tab contained some resource-intensive graphics (in my case it's an 1920x1080 gif image)). My PC runs the first 5-10 seconds without lag, then begins to slow down even the mouse, and if it still does not switch to previous tab, or open a window with the program, the PC freezes. To continue, I have to restart it (Hard-reboot).
