I don't know from when the issue existed on my laptop. I was looking at the bugtracker for i915 related issues and found it.

Affected versions:
I had packages for 5.5.13, 5.6.2, 5.6.3. All of them has this.
linux-lts does not show this behaviour. However, the bug report mentions 5.2 which I never tested.

Acer Predator G3-572 (the bug report also mentions an acer device so I thought this might be relevant)
7700HQ + 1050 Ti, using PRIME render offload
This task depends upon

See the i915 module does not use the kernel bugzilla for bug tracking.
Please also retest on drm-tip as requested in the link.

@loqs i could not get the kernel up and running. do they not accept reports made using other kernels at all?
Here are the stuff I used. PKGBUILD is from AUR/linux-drm-tip-git with some modifications. config and sphinx-workaround.patch are from core/linux, no modifications. linux.install is from AUR/linux-drm-tip-git unchanged.
config -
sphinx-workaround.patch -
linux.install -

Include a note in the bug report that drm-tip is not working for you. Do remember to include dmesg from a boot with drm.debug=0x1e log_buf_len=1M
linux.install is not needed and the PKGBUILD you are using does not call it.
