White lines flickering on boot

Hi all, noticed these white lines flickering on boot - see video. Just switched to Bazzite last week, never had this problem before in my previous Windows 11 install. Have attached more information to this post too about my rig. Monitor: LG UltraGear 27GR75Q-B 27" QHD 165Hz (connected to GPU using certified DP cable) Driver: Mesa 25.1.5; BIOS is fully up to date F18g Only thing that gets rid of it is changing my refresh rate cap from 164.96 to 144 then back to 164.96 on the Display settings... Would appreciate any help.
