@Rockus If you're checking ping in scoreboard, that's normal. Better look at pred value (cl_showpred 1)

[quakenet] <heinrich5991> Learath2: what's up with the gentoo package?

https://www.youtube.com/watch?v=Voy9vVbgSqI i've got this weird screen flickering on linux with ddnet at 144hz, so i wonder if this is a ddnet bug? The flicker doesn't happen on my desktop and also it doesn't happens on the browser (which both of them also run at 144hz). Some info that may help:

Weird screen flickering bug (144hz)

[quakenet] <Learath2> heinrich5991: gentoo was also complaining about the bundled libs, can give it another try now

@Ryozuki opengl3?

i tested with opengl3 on and off

17:27

with off its lot worse

17:27

but with on its like the video i sent

17:28

glxinfo | grep "OpenGL version"
OpenGL version string: 3.0 Mesa 17.2.8

17:28

this has something to do?

17:29

asyncrender off? ddnet 9?

17:36

other opengl applications?

last ddnet version

i mean try those

glxgears doesnt show this glitch (if that is a opengl application)

yes it is

"asyncrender off?" how to disable/enable this?

f1, gfx_asynrender_old 0

nothing changes with 1 and 0

I understand

mmm ddnet 9 starts on my non 144hz screen and mouse is really buggy

17:45

i just noticed i can notice the flicker a bit sometimes in the terminal too so it might not be ddnet related

disable compositing? use other DE/WM?

im using KDE

17:46

i also had this with gnome

I also noticed that my display has artificats with some specific patterns showing on screen, also annoying

you got 144hz? i always thought it may be some bad support for 144hz

no, 3840x2160@60Hz

and since i dont have this problem on windows, i bet it has relation to drivers?

I guess I should disable framebuffer compression

17:49

well, driver is split up in linux

17:49

so good luck finding out which part

saddo

17:49

well i know it uses a open source driver "radeon"

also, amd is trying to share as much code on win/linux as possible

17:50

try newer driver/kernel/mesa/etc

17:50

and search for bug reports

i got literally latest kernel

no problem with 120hz, 60hz?

i noticed it also on 120hz

17:50

gonna try 60

My trick is to use intel gpus only because amd and nvidia always gave me trouble on linux

but that sucks for me :( i spent 350€ on a good gpu

write an email to amd support?

i guess

17:52

i never had hope in those things tho

https://www.google.com/search?q=amd+radeon+linux+120hz+flickering

no flickering with 60hz

17:54

with 99 there are too

17:55

this is the closest bug report i could find https://bugs.freedesktop.org/show_bug.cgi?id=93826 but they say its fixed in 4.12 but i got 4.15 and i still have the problem

@Ryozuki did you try the new amdgpu drivers?

i tried using amdgpu instead of radeon, it works worse since it doesnt event detect that i can have 144hz

18:22

if u talk about amdgpu-pro

18:22

i havent got it to work

I used to have a r9 290x and it was much better

18:22

I used amdgpu not the pro one

amdgpu doesnt detect my 144hz and even flickers at 60hz for me

So weird

yes

Kernel version?

last, 4.15.3-041503-generic

18:24

i had 4.13 but no luck

18:24

decided to try last

18:24

and no luck

18:24

im doomed

You sure the driver loaded properly

e840206 Fix bundled pnglite - def-

well, tell me how to make sure of it if u can

You used to need an option to include the ucode for hawaii cards

18:26

Check your dmesg I guess

i had to put GRUB_CMDLINE_LINUX="radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1" on etc/default/grub to use amdgpu instead of radeon driver

18:26

and it worked

18:26

but as i said amdgpu worked worse

18:27

what does dmesg?

18:27

i see some logs

Dmesg is the kernel logs

ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver

18:28

:o

18:28

i see some radeon_dp_aux_transfer_native: 74 callbacks suppressed

18:28

but idk if thats good or bad

18:29

radeon 0000:01:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff

[quakenet] <deen> huh, no pnglite on archlinux

[    2.589764] [drm] amdgpu kernel modesetting enabled.

@Learath2 u know if this has relation?

[quakenet] <deen> that smells normal

18:32

[quakenet] <Learath2> that's a good thing

18:32

[quakenet] <Learath2> not really sure if it should happen with radeon tho

18:33

[quakenet] <Learath2> but wouldn't cause your flickers anyways

this all looks ok

Image attachment

18:35

idk i dont find any error

@deen thanks

@deen I tried all that. what was wrong with pnglite and wavpack?

20:56

@deen i.e. set(PNGLITE_LIBRARIES) should be the same as yours

20:59

@deen and I also tried bundled wavpack. the previous check allowed the user to plug in whatever version they have, including the bundled one

@Vanilla

21:20

wuips sry

21:20

@heinrich5991 do you know what those "626" data are related to?

21:21

don't have example right now

21:21

but when you get that packet, with 626....... something after
