Labels
Comments
Fixed in latest Steam beta. |
General-availability release 1646446125, 2022-03-05, still has this bug. See the issue description for workarounds. Beta 1646806235, 2022-03-09, fixes this bug. |
Hotfix shipped to stable yesterday that should fix this too. |
Yes, confirmed fixed: I swapped my Debian 10 machine from beta back to GA, and was given the same build 1646806235 that was previously in the beta. |

Your system information
Steps for reproducing this issue:
linux-hardened
kernelPlease describe your issue in as much detail as possible:
The
steamwebhelper
process that provides most of Steam's UI crashes repeatedly, resulting in Steam's main window (the Library, Store, etc.) being blank rectangles (usually black).The main Steam process repeatedly logs:
and also
~/.steam/root/logs/steamwebhelper.log
contains:as well as some noise related to Steam's crash-reporting mechanism.
~/.steam/root/logs/cef_log.txt
has the same message as in~/.steam/root/logs/steamwebhelper.log
.This was previously reported in #8373 as the second of three possible root causes for symptoms like these.
Workarounds
Choose any one of these:
-no-cef-sandbox
command-line option (typicallysteam -no-cef-sandbox
)linux-hardened
, switch to the defaultlinux
kernelSolution
Steam should do the equivalent of
-no-cef-sandbox
on these mostly older operating systems. This is not ideal, but is the best it can do. I have already provided Valve developers with a proposed change insteamwebhelper.sh
, which I believe is making its way through the release process.This is not necessarily the same bug you are seeing
Any bug that results in the
steamwebhelper
crashing will result in the same symptom where the main window is mostly black. This does not mean that the root cause is the same as the one described here.If the
-no-cef-sandbox
workaround does not work for you, then you are seeing a different issue and should report it separately.If Flatpak works on your system, and you do not have a setuid bubblewrap executable (typically
/usr/bin/bwrap
or/usr/libexec/flatpak-bwrap
), then you are seeing a different issue and should report it separately.If you are running the unofficial Flatpak version of Steam from Flathub, then you are seeing a different issue, #8421.
