Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Fabian, thank you for reporting this and helping make Ubuntu better.

1) To clarify, which update is what was correlated to this issue?

2) Is this still reproducible using the latest HWE stack as per https://wiki.ubuntu.com/Kernel/LTSEnablementStack ?
