Hi,
I have encountered this display issue since the last three updates (if my memory serves me right). So if I just open the project, the display is okay. But after clicking on the tabs or some pop-up windows several times (especially "Lexical search", I use it a lot), the display is like a glitch, see the .gif below.
Hope someone could help fix it. Many thanks!
