Daniel, yes it's indeed an NVIDIA GPU as the primary one (both primary and secondary are NVIDIA, an RTX A6000 and a RTX3090). The issue shows up for both the Chromium snap and any other Chromium based app I could find. I did have some Wayland & NVIDIA issues (glitchy rendering after typing on the keyboard) also on Mantic and before on this same system, but this symptom is a lot more extreme now on Noble.
Another observation as I messed around with reproducing this: I can see that on Noble hotplugging the display on Wayland doesn't really work (between these same NVIDIA GPUs), whereas on Mantic I didn't have the same problem. ** Description changed: - I am noticing two - - - Most of the time (3/4 desktop sessions attempted) all Chromium based + Most of the time (3/4 desktop sessions attempted) all Chromium based applications I have tested (Chromium, VS Code, Mattermost) fail to render themselves, on actual display panel presenting random garbage, - and when screenshotted, showing supposedly showing transparent pixels. + and when screenshotted, showing supposedly transparent pixels.
