smallbearayu Posted November 14, 2019 Share Posted November 14, 2019 Hi, I've run a stable Catalina 10.15.1 build on my Razer Blade 15 laptop. Everything works fine when the refresh rate is set to the default 144hz. However, if I change the refresh rate to 60hz, the screen glitches and it's totally unusable. Attached is a photo of the screen glitch. Any help is appreciated.
