This bug is awaiting verification that the linux/6.5.0-16.16 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-mantic-linux' to 'verification-done-mantic-linux'. If the problem still exists, change the tag 'verification-needed-mantic- linux' to 'verification-failed-mantic-linux'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.
