Running on Fedora-35, with KDE, Radeon RX6600, and Thunderbird 91.7.0, I can confirm that the above suggested fix does *NOT* solve the high-cpu usage problem. Even after setting "gfx.webrender.force-disabled" to "true" (and confirming "gfx.webrender.all" to be "false"), moving the mouse over either the message list or the folder list results in high cpu usage and much sluggishness; I can easily move the mouse more than fast enough to have the "hover highlight" not be able to keep up.
