It seems to fix the problem, but I'm not certain, because the behaviour started to become much less obvious after I sent this bug report (but before I tried your diff). I would see the occasional short flicker rather than reversions lasting nearly a second. With your diff I haven't seen any flickers. Going back to the Sep 9 snapshot kernel (which I was using when I filied this bug) I tried to find things that would trigger the problem the reliably, so I could try the same things with your diff, but I couldn't find a way to trigger it. (Mostly I just tried vigorously scrolling in Firefox assuming taxing the graphics card would trigger it, but that didn't work.) -- James

The dmesg on i386 without inteldrm disabled likely has some hints as to what is going on. When the drm drivers fail to attach they try to detach and reprobe vgafb/efifb. Your amd64 dmesg is with efifb not vgafb. You could try amd64 with csm/bios instead of efi to rule that out. > > OpenBSD 7.2-beta (GENERIC.MP) #0: Tue Aug 30 20:15:55 CDT 2022 > s...@jetsam.attlocal.net:/usr/src/sys/arch/amd64/compile/GENERIC.MP > real mem = 17018175488 (16229MB) > avail mem = 16354238464 (15596MB) > random: good seed from bootblocks > mpath0 at root > scsibus0 at mpath0: 256 targets > mainbus0 at root > bios0 at mainbus0: SMBIOS rev. 3.0 @ 0xaa62d000 (63 entries) > bios0: vendor LENOVO version "N23ET82W (1.57 )" date 07/21/2022 > bios0: LENOVO 20KHCTO1WW > acpi0 at bios0: ACPI 5.0 > acpi0: sleep states S0 S3 S4 S5 > acpi0: tables DSDT FACP SSDT SSDT TPM2 UEFI SSDT SSDT HPET APIC MCFG ECDT > SSDT SSDT BOOT BATB SSDT SSDT SSDT LPIT WSMT SSDT SSDT SSDT DBGP DBG2 MSDM > DMAR NHLT ASF!

As soon as I move the mouse with the trackpad the screen flickers. It does not happen if I use the keyboard. With all other snapshots before I never had that issue. I made a video for demonstration purposes: https://xosc.org/misc/flickr.mp4 [ At first, I move the mouse, then type on the keyboard and the screen stops flickering, then switch to Firefox, move the mouse again and the screen again starts to flicker ] Cheers Matthias >How-To-Repeat: Upgrade to latest snapshot on this type of machine. >Fix: Dunno.
