[Bug 1959747] Re: [upstream] Very high CPU and slow responsiveness in Thunderbird 91-102

[mgw]

OS: 5.15.0-52-generic #58~20.04.1-Ubuntu 
TB: 102.10.0
Nvidia Quadro 1000M
Intel Core i7-2760QM 
16 GB RAM

Same issue here plus time outs w/ 100% CPU utilization for approx. 20 sec. 
I noticed that the above mentioned paramter is gone (gfx...force-disabled) from the configuration. Reintroducing the parameter helps but doesn' fix the time out.

All this happend after latest upgrade to 102 w/ no changes in
configuration.
