Artrage Vitae is Unusable after Sonoma MacBook Update

[SirBlirmp]

Hello, I've recently updated my MacBook M3 to Sonoma 14.4.1 and Artrage Vitae and 6 are now unusable. When moving my canvas, the working area is filled with glitching white lines. I can deal with that, if needed, but it's a terrible distraction. Worse, when I'm painting, the brush begins to lag unacceptably after a few minutes. Oddly, if I go to the settings menu and close the window, painting returns to normal--but then returns to the lag. I've attached a screenshot.

I have a project due and I am desperate for a solution. I've even reset my Mac to factory settings and re-installed a fresh copy of Artrage to no avail. It appears to be a GPU issue after the update. I cannot use the software in its current state.

I am using an Xencelabs 24 pro display, but this glitch occurred after my factory refresh before connecting or installing drivers for this tablet.

Thank you for any assistance. As I mentioned, I am desperate.
