Basically, the arm goes all over the screen.

Doesn't happen every time; occurs randomly

[octacian]

I can confirm this on Ubuntu 17.04 as well. Except for me, it happens nearly all the time, and not only that but I've also had the hand disappear entirely for a time.

It is pretty sad how little these PRs have been tested before merge... lol
/me puts it on his list to learn how to test PRs

[kilbith]

Get back to an older commit (git reset --hard 51104d9cd4), recompile and tell me if it fixes your issue.

[paramat]

octacian, it was tested but didn't occur for the tester, if you want PRs tested more thoroughly then you have to test them yourself.

[kilbith]

People, can you please answer these questions:

1. What's your monitor refresh rate?
2. What's your FPS max limit?

[lisacvuk]

1. 60
2. No limit, but doesn't cross 60

[ElementW]

a80ecbe is affected by the bug

[lisacvuk]

Seems to be triggered on teleporting

[azekillDIABLO]

a80ecbe is affected by the bug

what do you mean?

[octacian]

I can confirm that the issue only seems to happen after teleporting, being via /teleport or /home.

And the two questions:

1. and 2. 60

[mtango688]

Seems like it's related to yaw. I can carefully pitch up and down without too much effect, but any amount of yaw will make it flicker, when the effect does come into play.

[ElementW]

@azekillDIABLO

what do you mean?

The only thing it could mean, you dummy: I confirm the bug happens with Minetest server+client on commit a80ecbe.

[Fixer-007]

Had something similar, fps_max = 100, fps in game was around 60, engine 0b3a8de.
Demo:

Get back to an older commit (git reset --hard 51104d9), recompile and tell me if it fixes your issue.

Have not seen that big bug-motion on 51104d9 (with limited testing back then), I've had different one.

[kilbith]

Unfortunately, I'm not able to reproduce the issue after teleporting.

But disabling the arm inertia by default should be considered.

[Fixer-007]

Try reproducing it on actual server, for example Hometown, find a spot, /sethome it, then go into completely different area and do /home.

[kilbith]

Try reproducing it on actual server

Irrelevant, it's a client-side effect entirely. Also singleplayer mode is a server too.

[Fixer-007]

Try my config. Issue is easily reproduced for me, at least on hometown server:

anisotropic_filter = true
bilinear_filter = false
creative_mode = true
enable_damage = true
enable_waving_leaves = false
enable_waving_plants = true
fast_move = false
free_move = false
leaves_style = fancy
maintab_LAST = online
menu_last_game = minetest
mip_map = true
node_highlighting = box
server_announce = false
server_dedicated = false
trilinear_filter = false
viewing_range = 160
fps_max = 100
mg_name = v7
tone_mapping = false
noclip = false
texture_path = 
sound_volume = 0.6
enable_shaders = false
fog_start = 0.7
enable_bumpmapping = false
enable_parallax_occlusion = false
enable_waving_water = false
generate_normalmaps = false
smooth_lighting = true
enable_local_map_saving = false
mesh_generation_interval = 5
autosave_screensize = false
enable_client_modding = true
fixed_map_seed = 
minimap_shape_round = false
enable_server = false
show_debug = true
fsaa = 0
port = 30000

[mtango688]

It doesn't happen if you just teleport. You need to be moving the camera around during teleport.

[kilbith]

I still fail to reproduce, sorry.

EDIT: Got it now.
