When using SSMS, and switching between query tabs, sometimes the screen does not refresh/repaint and it continues to show the content of the previous tab. Some users also reported that their text labels/menus appear blur in SSMS and icon disappears on move-over.
This issue is most likely due to Hardware Acceleration. You can turn off Hardware Acceleration in SSMS by following these steps:
Go to Tools menu and select Options. In General Section, you can see Visual Experience Section. Here you need to uncheck following checkbox / options:
- Automatically adjust visual experience based on client performance
- Enable rich client visual experience
- Use hardware graphics acceleration if available
Press OK button and restart SSMS.
