Since update to HWE kernel 5.3.0-46-generic I am experiencing frequent (every couple of minutes) GPU hangs and reset) manifesting as 2-3 seconds freezes of the GUI (other than the mouse pointer). These GPU hangs did occur in earlier kernels in the 5.3.0-xx series but were infrequent (once or twice a week)
No particular triggers identified although have Chrome / Chromium running with Hardware Acceleration enabled does appear to increase the frequency.
I have seen incidences of these hangs in jounralctl output using previous kernels in the 5.3.0-xx series but they were very infrequent (one or twice in a week of daily usage)
