Non-smooth arrow scrolling

[bubbles]

Hello all; the title pretty much says it all. In SM5 I'm getting microlag in the scrolling of the arrows -- just enough to be noticeable and annoying.

In the old threads I found the issue was often related to Vista. The solutions related to swapping between d3d/opengl or WaveOut audio drivers. I am running Debian testing with ALSA so none of those seem to apply to me. :( (Edit: I am using an Intel GMA HD 3000 graphics adapter. I have direct rendering (acceleration) with OpenGL.)

I built the game from hg yesterday. I have tried using windowed mode and full screen with vsync on and off but the problem is always there. I'm not sure where to turn next. If I can get some sort of verbose logging or instrumentation to identify where the latency is I am happy to turn it on and try to figure it out.

Does anybody have any ideas for me to try? I'll really appreciate it, thanks. I'll post my console log below in case something in it is helpful...

Yeap. I can confirm that. I `ve encountered same problem while I was testing fresh reinstall of windows xp on friend`s netbook. It also had Intel Graphic chipset.
oITG and SM3.9 run ok.

Thanks for the confirmation. If anyone has any suggestions I'm willing to give them a shot, but I've managed to get oITG running fine so I'll run with that for now.

to my knowledge it's an issue with recent versions of ALSA, not sure though since none of my computers have this issue.
