#StackBounty: #debian #wifi #monitors #lag Screen lag spikes when WiFi on

Bounty: 50

I have a strange problem: Whenever WiFi is turned on (doesn’t matter if connected or not), my screen freezes for a few frames every ~2-3 seconds. This does not affect the cursor, but everything else.

Specs:
Schenker XMG A507-vsy
Debian buster/sid (x86-64)
Cinnamon 3.2.7
Kernel 4.9.0-6-amd64
CPU Intel Core i7-7700HQ
GPU Intel Corporation Device 591b
Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)

When searching for things like “wifi screen lag spikes” or similar, I of course get people who have lag spikes in online games, so that doesn’t help me.
