Bug#680619: nullmailer: dpkg-reconfigure corrupts IPv6 zone index in "remotes"
Pretty sure the following contraption in the postinst script is responsible: 36 echo "$RET" | sed -r -e ':a s/(\[[^]:]*):/\1=/; ta' \ 37 -e 's/[[:space:]]*:[[:space:]]*/\n/g' \ 38 -e ':b s/(\[[^]=]*)=/\1:/; tb' \ 39 -e 's/[][]//g' > /etc/nullmailer/remotes Unfortunately I am not completely sure what happens here (and what could possibly removed or fixed).

Bug#1030609: Sluggish performance in Bookworm (and Bullseye since version 0.9.13+dfsg-2+deb11u1)
Package: x11vnc Version: 0.9.16-8+b1 I am using VNC via SSH using x11vnc to access my remote desktop from home. x11vnc is called with the following arguments: x11vnc -quiet -safer -localhost -nopw -once -display :0 Since upgrading to Debian Bookworm about half a year ago, update performance degraded rapidly and the following messages started showing up in the output from x11vnc on various events (opening of windows, focus changes): PORT=5900 The VNC desktop is: localhost:0 *** fb_push ublen NOT ZERO: -1616838418 *** fb_push ublen NOT ZERO: 932745215 *** fb_push ublen NOT ZERO: -1644826 *** fb_push ublen NOT ZERO: -1711237889 *** fb_push ublen NOT ZERO: -1711237889 The same issue has been reported by at least one other user as well in the Debian forums [1]. After erroneously assuming this to be caused by a patch that was backported to Bullseye (see [2] and [3]), it appears now to be a packaging bug as recompiling x11vnc locally fixes the issue.

Bug#1027043: libvncserver1: 0.9.13+dfsg-2+deb11u1 make x11vnc slow. 0.9.13+dfsg-2 works fine.
I was able to fix this by removing patch 0003-rfb-increase-update-buf-size.patch and recompiling this package, as well as x11vnc. I am guessing this might actually be a problem within x11vnc.

Bug#981368: xserver-xorg-video-intel: Xserver becomes unresponsive with some worloads. maybe related to video rendering
Looks like this was actually a bug in the i915 module: https://gitlab.freedesktop.org/drm/intel/-/issues/2905 There is a linked issue #2923 "deadlock in intel_atomic_cleanup_work (kernel 5.10.5)" that seems to fit the descriptions in this thread here. After upgrading to a custom 5.10.17 kernel, I don't seem to experience the same issue anymore while still using the intel Xorg driver. I agree that this report could be closed now. Cheers and thanks for keeping the intel driver alive, still performs significantly better on my particular system than the modesetting driver! -- Jörg Mechnich Stellv.

Bug#954283: gzip: produces corrupt output files on armv5tel
Package: gzip Version: 1.10-1 Severity: critical Justification: causes serious data loss Dear Maintainer, the stock package from testing provides a broken gzip binary which will produce corrupt output that fails CRC checks. Compiling the plain 1.10 sources generates a working gzip binary. The issue seems to be caused by > DEB_CPPFLAGS_MAINT_APPEND := -DUNALIGNED_OK in debian/rules. After commenting the line and rebuilding the package properly, gzip works as expected. gzip-1.9-3 from stable obviously works as well. Please let me know if I can assist in any way during the resolution of this issue.
