Thanks TheMarkus1204. The problem seems to be the hardware acceleration in Chrome on the M1/M2 chip with Metal. I changed the ANGLE graphics backend under chrome://flags to OpenGL and it is working now. I hope Google / Roll20 will fix this as Apple will drop the OpenGL support: Choose ANGLE graphics backend Choose the graphics backend for ANGLE. The OpenGL backend is soon to be deprecated on Mac, and may contain driver bugs that are not planned to be fixed. The Metal backend is still experimental, and may contain bugs that are still being worked on. The Metal backend should be more performant, but may still be behind the OpenGL backend until fully released. – Mac Cheers, Marc
