Thunderbird Problem
I'm running Thunderbird 138.0.3 (release update channel). I had an update in the past few days and now it is having a problem. Thunderbird starts OK but it I use another program for several minutes when I go back to Thunderbird its window is not visible. Looking at my system monitor Thunderbird is using a lot of CPU. The only way I can proceed is to kill Thunderbird from the system monitor. No crash report is generated. Running in safe mode does not help.
If I run Thunderbird from a terminal I get: $ thunderbird [64132] Sandbox: CanCreateUserNamespace() unshare(CLONE_NEWPID): EPERM ATTENTION: default value of option mesa_glthread overridden by environment.
This seems pertinent as it it to do with graphics but the web seems to suggest it in not important.
I have copied the Troubleshooting information to a text file and so can share it but it is quite large does not seem appropriate to include it here.
Any help gratefully received.

I'm running Thunderbird 138.0.3
The latest version at https://www.thunderbird.net/thunderbird/all/ is 138.0.2.
Assuming you're running a Thunderbird version provided by your distribution you may be better off asking in their support forum.
In general, turning off hardware acceleration in Thunderbird settings may help. Alternatively, try the vanilla Thunderbird version from https://www.thunderbird.net
Apologies "138.0.3" was a typo. I'm using "138.0.2".
I'm not using the version provided by the distro as I'm not happy with snap. I'm using http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt/
