OK.
there's a whole stack of people reporting this occurring, running the
full range of window managers.
Does DRI2 vs. DRI3 have any effect on it?
hmm, good question. i'm running with "DRI" "true"
Valid values for "DRI" setting are "2" or "3".
(so don't know if it's 2 or 3),
This tells you which version apps get:
LIBGL_DEBUG=verbose glxgears
LIBGL_DEBUG=verbose glxgears
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/i965_dri.so
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/i965_dri.so
libGL: Can't open configuration file /home/lkcl/.drirc: No such file
or directory.
libGL: Using DRI2 for screen 0

Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
303 frames in 5.0 seconds = 60.424 FPS
212 frames in 11.7 seconds = 18.079 FPS
huh. so i _thought_ it was going to be DRI3. that's supposed to be
the default, isn't it?
You need it enabled in Intel DDX build, in X configuration, and Mesa
build (with building done with suitable deps present).
On normal distros, support should be built in, but not necessarily
enabled for run-time by default. In your own builds you need to make
sure you enable support for DRI3 (= use "--enable-dri3" configure option).
other people will have different settings.
It would be interesting to know whether there's any correspondence with the
DRI setting, and what exact Mesa & X versions they have.
looks like i'm on debian 13.0.6-1
???
$ cat /etc/debian_version
eeee this is gonna be fun - i'll relay the request and get back to
you: might take a while, there's lots of people / lots of different
projects.
some people are *not* able to repro the problem which is a good datapoint.
