When opening an individual email in Thunderbird, frequently the window which opens with the email is flawed. Usually the window has streaks of color starting in the upper left corner and spreading out like a fan throughout the window. (see attached image).The computer is a Dell touch screen - Inspiron 24 All in One 5400 FHD Touch display with Intel Iris Xe Graphics. If you roll the mouse over the screen, it corrects. Thunderbird is the only application where these errors in the display occur. Thank you for checking this out. Don Turner

Does it look better in safe/troubleshoot mode (hold Shift when launching TB)?

If it does, first thing to try is disable hardware acceleration in Preferences/General/Indexing, if it's enabled in normal mode, then restart TB in normal mode.
