--- Comment #8 from noreporter <phamtruonggiang...@gmail.com> --- I would like to update on this problem, I have managed to identify the issue with how the text's colors are being displayed on my monitor , which is the refresh rate I set for my monitor( I report this problem when monitor's refresh rate at the time was 175 Hz) . When I decrease the refresh rate of my monitor from 175 Hz to 144 Hz it solved the problem. I guess this is an NVIDIA problem so I am going to report this to NVIDIA. This problem is solved, thank you -- You are receiving this mail because: You are watching all bug changes.
