Tbird 115 on 15.4 - Write Message - Menu Autohide only 1/2 Hidden - Grating appearance changes

All, Zypper up pulled in Thunderbird 115. It is horribly different from 102 and does not respect my color or theme choices that 102 did. Further, the interface is a bit buggy. The new-message window menu-autohide - doesn't completely hide the menu, you can see the bottom of all menu entries under the window titlebar: https://paste.opensuse.org/pastes/8f0de87e7c53 What changed to radically to give tbird 115 such a different and unpleasant look? When I have tabs open in thunderbird, you can only see the active tab, all others are black-text on black-background ?? Is this libadwaita rearing its ugly head? -- David C. Rankin, J.D.,P.E.
