Plasmashell crash
Backtrace plasmashell fedora 35 Firefox console Error |
||
Some Additional Information:
1. Using firefox nightly from officially provided tar.gz
2. Also tried to reproduce the crash after refreshing firefox, with following observations:
- Crash is no longer unrecoverable on a fresh install of firefox. The panel always comes back.
- enabling gfx.webrender.all crashes the firefox after 1 or 2 tries of dragging the tab
- enabling layers.acceleration.force-enabled increases the chances of crashing on 1st try.
3. Sometimes logout doesn't resolve the issue. Full reboot is required.
Can you please attach a backtrace of the crash? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports Created attachment 143500 [details]
Backtrace plasmashell fedora 35
Was able to reproduce the issue on fresh install of fedora 35. Let me know if anything is still missing. It was difficult to reproduce the crash on with gdb for some reason. Steps and Observed results still the same. Also observed Timeout reading from pipe error on moving firefiox tab in console. Attaching image for the same.

Firefox console Error
As described, it works for me - i.e. I can drag a tab from Firefox 93 to the desktop to create a new window, and Plasma 5.23.2 doesn't crash. However, when I set "layers.acceleration.force-enabled" to "true", dragging a tab to the desktop will no longer create a new window.

Try enabling gfx.webrender.all as well. Make sure Fission is enabled and web gpu from about:preferences#experimental . My point is whatever the settings, plasma shell should not crash especially on Wayland. It is better reproducible on arch. On stable fedora it might take a couple of tries. Additionally for some reason DrKonqi never appears. (In reply to Shubham Arora from comment #7) > Try enabling gfx.webrender.all as well. Make sure Fission is enabled and web > gpu from about:preferences#experimental . So I've enabled gfx.webrender.all, fission.autostart and dom.webgpu.enabled, restarted Firefox and dragged about 20 tabs from different websites to my desktop without a crash. This is on OpenSUSE Tumbleweed with the MozillaFirefox package 93.0-80.3 from the home:trmdi:Tumbleweed repo (because it has the global menu patch), with KDE Wayland 5.23.2. I'm not saying that this issue doesn't happen, only that I can't reproduce it yet. If/when it happens, I will post again here. Either way it should not bring down Plasmashell.
