This morning its broken again. Can't see any text inside of intellisense because its black text on dark background.
I tried restarting SSMS, disabling SQL Complete, but no joy.
Bizarrely, switching the theme from Blue to Light, and then back again, fixes the problem.
I am having the exact same problem. Thank you for the heads up on changing the color theme that also worked for me. This has happened intermittently since I upgraded and it is getting very annoying so I really appreciate the work around.
This happened to me right after the 5.7.210 update.
The workaround I discovered:
1. select "Tools" from the SSMS menu
2. select "Options"
3. expand "Environments"
4. highlight "Fonts and Colors"
5. select "Ok" (note: don't need to change anything if you have Identifier fore/background colors configured correctly)
This workaround overwrites at least the back/foreground colors of "Fonts and Colors -> Identifier" so SSMS is able to display text.
This should give devart developers a hint where to look to fix the problem.
