Version: 1:7.6 & 1:7.7
Good day Debian world,
I'm curious if you've observed a performance regression in Xorg versions
above 1:7.5 (i.e. any version that can use DRI3) for integrated Radeon
chips using the r300 driver.
At least in Ubuntu, when using any version above 1:7.5.0-1, tearing ensues,
regardless of the presence of a xorg.conf config file to enable/disable
options to improve framerate. Enabling DRI3 only worsens the performance
regression, and accentuates tearing.
I've been advised to bisect Xorg versions to pinpoint the problematic
package version, but my machine is rather old (10 years) and I ran out of
disk space cloning the repos to do so. I retired from the IT industry, now
turned into a guitar builder, so I haven't really upgraded anything else
besides hand tools, but if there's a problem in linux, I feel the need to
In case you've encountered such a problem, I've filed reports both in
lauchpad and upstream for anyone to read.
If this regression isn't present in Debian, please disregard this message.
