micro dropout's playing video's / card games or just scrolling in an terminal.

[sixpack13]

Hallo

is it just me ?

in an terminal running "man man" constantly scrolling the pages up or down: it
scrolls some line/a page (~2 seconds), stops, scrolls some lines, stops ...

Also if I play video's or card games I notice micro dropout's.
Video plays 2 seconds fluidly, then pauses/stucks for a ~1/4 second, plays 2 seconds
fluidly, pauses/stucks for a ~1/4 second, and so on.

it seems like a video-buffer isn't constantly filled to play videos smooth.

I exclude hardware error cause:
- the box is just an half year old and I tested a card game under windows 7 without
dropouts.
- I tested with another monitor.

I tested an elder kernel ~4.13.x without an solution.
I tested under wayland and Xorg-Gnome.

F27 is up date.

Any hints to debug/troubleshoot this ?
Or is it just me ?

You might want to mention a) which terminal program you use, and b)
which graphics driver you have. Either or both may be relevant.

I have radeon graphics, I can run man man in a gnome terminal
flawlessly.  If you give a game name that has problems, I can try it.

Is there anything running in top that might be creating interrupts?
Compile, system update, locate scan, etc.

Thanks @stan for testing.

top is without any hints. 
Games is xskat.


anyone with an intel IGP (i915) who could test ?

I installed this and tried to play.  I had no idea what I was doing,
but there were certainly no delays or dropouts.  Every response was
quick.  This is not a game I'm going to pick up quickly, it seems quite
complicated just from reading the rules, so I doubt I can help beyond
that.

thanks again.
and a happy new year !

It is sufficing to watch card dealing to see many problem.
I see a dropout or interrupt on the way a player get his cards during dealing: deal,
moving cards, -stuck/delay-, moving cards further.

Anyway I think one with a intel onboard graphic need to test this.

for the record I opened a bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=1529986


P.S.
the card game isn't that complicated. It's about mathematics and strategy...
