Bug or Regression?

Bug

Description

see https://github.com/hyprwm/Hyprland/discussions/4858#discussioncomment-8610673 for video

scrollbar indicator (as well as URL-labels when shown, Ctrl+o in default foot conf) seems to be treated specially. as, you won't believe, it is affected by Hyprland's rounding setting. which shouldn't happen I suppose

maybe this could help to investigate the root cause

as mentioned in discussion, force_introspection = 1 eliminates glitches for me, but it's likely a strange coincidence on my end

How to reproduce

to properly reproduce you need pad value to be greater than default 0 and probably some larger font size than default 8

try launching

foot --config=/dev/null --override=pad=8x8

and zoom with Ctrl+= or Ctrl+MouseUp

then just print some long stuff and scroll

Crash reports, logs, images, videos

No response

[vaxerski]

the scrollbar really shouldnt be a subsurface...

[BeyondMagic]

Can replicate.

[bvr-yr]

the scrollbar really shouldnt be a subsurface...

report upstream? I'm afraid the answer might be like "Hyprland problem, it works in sway"

[1player]

Good for tracking it down to the pad setting. I can replicate as well, and here's my config:

[main]
font=PragmataPro Mono:size=13
pad=4x4 center

[NikkSaan]

I noticed the glitch disappeared for the windows in which I set a theme with theme.sh. But that causes foot to have a slightly higher cpu usage. I don't know If this observation will help you guys debug the problem, but It might serve a temporary fix for some.

I am experiencing glitched scrollbars, as well. +1

This seems to be fixed with latest hyprland, for me, it works well:

nothing changed for me on 3fd6c1b30e5397432c4640286efaf52a6891f71c foot version: 1.17.2-31-g0bf5a7e9 (May 24 2024, branch 'master') +pgo +ime +graphemes -assertions

@rtgiskard did u use extra padding and larger font?

@rtgiskard did u use extra padding and larger font?

For me, the pad is always pad=4x2, I do have the same problem before, but not find any glitch recently, the foot version is v1.7.2 from archlinux official since 2024-04-21, and I switched to hyprland since 2024-05-01.

The glitch is there for several days, then I just get used to it, and recently find no glitch at all. Both a54ab301, dd274b72 works well for me. Test with the reproduce steps above.

Well, it's still there, but only for scroll cursor moved passive:

. open a foot window, run tail -f /run/user/1000/hypr/*/hyprland.log, then scroll up with mouse so that the scroll cursor is displayed . open another window, move your mouse around (to generate more logs output for the above tail), you will see the scroll cursor get moved up with some lightly glitch (but much better) . if just scroll in current foot window, I can't reproduce any glitch like what it was.

[bvr-yr]

some progress on 8412ffcc42012888757cd00a004871e8bc353cf2

now I can observe glitches only on tiled windows
