Nvidia?

or try to install hyprland-git see if it still persist. reboot required.

when did this happen? fresh install? after update? any helpful input?

@kRHYME7 sorry for the delay my workload has been crazy lately.

Yes I do have NVidia:  GPU : NVIDIA GeForce RTX 3060 Lite Hash Rate
​​ ​  GPU Driver : NVIDIA 550.78

I believe, by the time of writting, hyprland-git might be broken, I will try later.

[kRHYME7]

have you tried downgrading GPU driver?

[psilvaricardo]

@kRHYME7 sorry for the delay.

I haven't tried, how do you downgrade GPU driver? currently I have:

It was an easy fix for me with just one environment variable ELECTRON_OZONE_PLATFORM_HINT=auto for electron 28+ apps applicable, i'm using this one ELECTRON_OZONE_PLATFORM_HINT=wayland and no issues so far. And the --disable-gpu flag "fix " is using vaapi that makes electron apps able to use the gpu so no need to disable it, but some work needed to be done, but then you won't need any electron flags(nvidia proprietary nvidia-dkms needed tho) but can't guarantee it to work flawless tho, could be broken again by new release. Follow instructions as on Hyprland Nvidia wiki and VAAPI described. Hope this helps you.

@dieBakterie thanks for your advice, I have not been able to update because there is some issues when updating to the latest version of hyprland-git, I will try again later
