With libsdl-1.2.5-r2, frozen-bubble, orbital-eunuchs-sniper and tuxracer run perfectly well - I'm using XFree 4.3 with ATI's proprietary drivers on a Radeon Mobility 9000, and other games/OpenGL apps never cause problems. Under libsdl-1.2.6-r1, snipe2d and tuxracer give incredibly jerky framerates, and frozen-bubble crashes when you try to start a game. With r2 of the same package, frozen-bubble appears to work again, but the problems with snipe2d and tuxracer remain. SDL speed & stability is quite important to me, as I develop graphics applications based on SDL myself... Reproducible: Always Steps to Reproduce: 1.Emerge libsdl-1.2.6-r2 (or r1) 2.run snipe2d or tuxracer 3.erm....observe the results Actual Results: poor performance in both games (possibly others that use SDL; of the 3 I have installed, these two demonstrate the problem). Expected Results: No problems, as when using libsdl-1.2.5-r2 Portage 2.0.49-r15 (default-x86-1.4, gcc-3.2.3, glibc-2.3.2-r1, 2.6.0-test6) ================================================================= System uname: 2.6.0-test6 i686 Intel(R) Pentium(R) 4 CPU 2.80GHz Gentoo Base System version 1.4.3.10 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-march=pentium4 -O3 -funroll-loops -fomit-frame-pointer -fprefetch-loop-arrays -pipe" CHOST="i686-pc-linux-gnu" COMPILER="gcc3" CONFIG_PROTECT="/etc /var/qmail/control /usr/share/config /usr/kde/2/share/config /usr/kde/3/share/config /usr/X11R6/lib/X11/xkb" CONFIG_PROTECT_MASK="/etc/gconf /etc/env.d" CXXFLAGS="-march=pentium4 -O3 -funroll-loops -fomit-frame-pointer -fprefetch-loop-arrays -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="sandbox ccache autoaddcvs" GENTOO_MIRRORS="http://gentoo.oregonstate.edu http://distro.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 crypt cups encode foomaticdb libg++ libwww mad pdflib spell xml2 xmms gdbm berkdb slang tcltk sdl tcpd pam perl imlib gtk mng openal -oss dga cscope X gtk2 gnome alsa -qt -kde -debug mmx sse -3dnow acpi -apm -arts avi cdr dvd -esd -fbcon gif gpm gstreamer imap joystick jpeg mikmod mozilla mpeg ncurses oggvorbis opengl png quicktime readline samba ssl tiff truetype wmf xv zlib -nls -python java -svgalib -svga -motif moznocompose moznoirc mozsvg"
I have the same problem with libsdl-1.2.6-r2 and pydance. The game runs fine with libsdl-1.2.5-r2, but slows down to unplayable when using libsdl-1.2.6-r2. This should be considered a major bug.

Just tried libsdl-1.2.6-r3 and this bug is still present. Has anyone looked into it?
I've never been able to reproduce the symptoms described by the original bug submitter so I for one haven't looked into it.
The alsa driver in SDL is having problems it seems. USE="oss -alsa" emerge libsdl should resolve the performance issues until libsdl gets itself straightened out.
It would seem to make sense that it's audio related - it was a while ago, but I seem to remember that my own SDL apps (two of them, one using OpenGL, neither using sound) ran fine. I'm kicking myself for not having thought of that. I'm glad a solution's been found, and I might try it out some time on my machine, but currently I'm trying to avoid using OSS except where absolutely necessary (same for GTK 1, trying to keep my install 'legacy free'); since there's no pressing reason for me to update SDL immediately, I'll probably just wait for future versions and see if it sorts itself out.
Still having this bug with libsdl-1.2.6-r3
same here, just to add.... I'm running kernel 2.6.2's alsa
try out 1.2.7 for us please
Much better! I only had a brief look, but sinpe2d, frozen-bubble and tuxracer all run, and the stuttering is gone. I haven't updated my kernel or switched from ALSA to OSS, so if anyone else having the problem would like to try out 1.2.7, pending their results I'd say the problem's gone.
Ok, we havn't heard any complaints about 1.2.7 so I'm marking this bug as FIXED.
