It seems that windows don't repaint when I open a calculator, Bluefish or gEdit. It's impossible to use those applications.
example of the problem in Calculator
example of the problem in gEdit
I have: - HP Compaq Elite 8300 Ultra-slim - CPU: Intel Core i5-3470S - Graphics: Intel Ivybridge Desktop with dual screen setup - Gnome: 3.28.2 - Ubuntu 18.04.1 LTS
No 3rd party graphics drivers installed or found for this system.
Does anyone know what should I try to fix this problem?
