In most cases, glitching or visual artifacts appearing on the screen in Magma are not caused by Magma itself, but rather by issues or bugs in the code of either the browser, or graphics card drivers used by your device.
First make sure you're using recommended browser that is up-to-date.
Try using a different browser. For example, if you are experiencing glitches in Chrome, try use Firefox instead.
Previously, we had the option to disable graphics acceleration, but we recently removed support for CPU rendering: https://help.magma.com/en/articles/8922956-hardware-acceleration-gpu-cpu
