The Bugbug bot thinks this bug should belong to the 'Core::Graphics: Canvas2D' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I can reproduce this issue on Nightly120.0a1 Windows10.

Regression window:
https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=d619ad58f951905f48571e1804cf9132885ce885&tochange=502f57bb0ebbce52ba15616a4aa213f2478f8e1f

FWIW, setting gfx.canvas.accelerated to true OR gfx.canvas.azure.backends to skia seems to fix this.
