I thought I got the solution to crashes with CEF 77+ when used with jemalloc (and managed to find a workaround for the SL Marketplace products pages crashes), but I noticed today that the web plugin based on CEF 81 also crashes in the SL status web page.
Of course, I could "simply" disable jemalloc in the viewer, but then it would cause a (very significant) performances loss.
I will therefore likely revert the Linux web plugin to the last working CEF version (v74)...
