The windows break when moving

English Hardware

I installed opensuse leap 15.3 on my pc and the windows can’t move smoothly and they break like vsync problems.
I set “Rended bacground” to other modes in “Compositor settings”. But the problem was not solved.

The problem was solved only when i set “Tearing prevention (vsync)” to “Full screen rapains”. mode.

Now i have both 15.2 and 15.3 with different homes (different desktop settings) and i can compare them. just the difference is the boot method, 15.2 is mbr and 15.3 is uefi

My gpu is intel hd530 and i installed drivers like previous version (leap 15.2).

Is it a bug?
Could it be related to boot flags?

You hit the same i915 bug I hit on my laptops - there is something they broke in the i915 module.

you can add to /etc/default/grub this line GRUB_CMDLINE_LINUX_DEFAULT== to the end before the " add i915.modeset=0

I bet that will fix it.

don’t forget to to do the ‘grub2-mkconfig -o /boot/grub2/grub.cfg’ afterwards to update.

you can follow my pain here:
