Aurorae rendering buttons NVIDIA vs INTEL

OS: KDE Neon 5.10.5
GPU: Nvidia GTX 1050Ti
Driver: Nvidia 384.69
Aurorae Theme: Arc-Dark (https://www.opendesktop.org/p/1167637/)

With propietary Nvidia driver Aurorae have wrong rendering buttons (close, minimize, maximize and etc)
Used settings by default on systemsettings (size buttons, window frames and etc).
This not reproduces on Intel GPU, but bugged on propietary NVidia driver
File for compare attached.

Xorg.conf:

xrandr --prop:

Also used scripts for ArchWiki
/etc/profile.d/kwin.sh:
export KWIN_TRIPLE_BUFFER=1

Used OpenGL >= 2.0 as rendering backend

PS: I'm change rendering backend to OpenGL 3.1 and XRender, but it's not solve problem.

Sorry, but that is nothing we can influence. Please note that 3D hardware does not guarantee pixel perfect rendering.

Comment 3 varlesh 2017-09-07 15:19:39 UTC

Disagree, see screen other elements and icons render right - with pixel align:

Comment 4 varlesh 2017-09-07 15:21:32 UTC

Why RESOLVED INVALID? Why on Intel this render right  but on NVidia not?
