I'm sure of that because I use HDMI every day, at work or at home. And I checked my apt/Synaptic's history. Nothing else was updated this day apart kernels. I updated GS and Mutter to 3.36.9 *way after* having experienced the issue for the first time.
And kernel 5.8 hwe is working nicely with HDMI...
Please note that I did have some partially similar issues with 5.10 oem with my Dell WD15 dock (2 displays) at work: after unplugging the usb-c, I have to force the shutdown and sleep is broken. I absolutely don't know if this is related to this bug here.
