Yes I just did that now. They need to be set as an environment variable though (like `env QTWEBENGINE_CHROMIUM_FLAGS="--disable-seccomp-filter-sandbox" ./run`) because if I just append them to `./run`, bash thinks they are a file to be opened with `./run`.

All the suggested flags (`--disable-seccomp-filter-sandbox`, `--no-sandbox` and `--single-process`) allow me to open Anki without the `failure in syscall` error, and the WebViews actually display what they are supposed to.  
However the following error appears every time a WebView closes:

```auto
Caught exception:
Traceback (most recent call last):
  File "/home/zjosua/sw_dev/anki/qt/aqt/webview.py", line 37, in cmd
    return json.dumps(self.onCmd(str))
  File "/home/zjosua/sw_dev/anki/qt/aqt/webview.py", line 123, in _onCmd
    return self._onBridgeCmd(str)
  File "/home/zjosua/sw_dev/anki/qt/aqt/webview.py", line 529, in _onBridgeCmd
    if self._shouldIgnoreWebEvent():
  File "/home/zjosua/sw_dev/anki/qt/aqt/webview.py", line 522, in _shouldIgnoreWebEvent
    if sip.isdeleted(self):
TypeError: isdeleted() argument 1 must be sip.simplewrapper, not AnkiWebView

```

These didn’t show up when I didn’t pass any arguments (and got just blank WebViews), but I was able to provoke something similar when I started navigating with shortcuts:

```auto
Caught exception:
Traceback (most recent call last):
  File "/home/zjosua/sw_dev/anki/qt/aqt/main.py", line 997, in onStudyKey
    self.moveToState("review")
  File "/home/zjosua/sw_dev/anki/qt/aqt/main.py", line 658, in moveToState
    self.clearStateShortcuts()
  File "/home/zjosua/sw_dev/anki/qt/aqt/main.py", line 991, in clearStateShortcuts
    sip.delete(qs)
TypeError: delete() argument 1 must be sip.simplewrapper, not QShortcut

```
