Public bug reported:
I was used to use 20.04 where the problem did not appear.
I installed 22.04 from scratch (not a reinstall) on the same machine.
Now after a day-long session the system has lags. In particular
- the mouse has random long lags (>1s)
- when I type I get short keyboard lags (<1s) and the following annoying bug:
every now and then the lag is followed by one of the keystrokes that occurred
during the lag being repeated like 10 times (and it does not look like a
mechanical issue)
Room temperature right now is 30C due to long lasting heat wave in Toulouse,
this may be related.
However I doubt it: a system restart usually solves the problem for a few hours.
