Problem je, ze pri scrollovani na touchpade v prehliadaci Firefox(obcas), ale hlavne v Evince pdf viewry, pri rychlejsom rolovani, sa obraz akoby pomalsie zobrazoval v porovnani s pohybom prstov po touchpade.Vyzera to ako vlnky, akoby sa obraz hybal,"ako, ked hodite kamen do vody".Neviem to lepsie popisat. Preto som hladal, ako prinutit libinput,aby scroloval pomalsie.Nasiel som,ze mam do
/etc/X11/xorg.d.conf/40-libinput.conf pridat nieco na styl>

Toto vsak nefungovalo :(
Nestretol sa niekto s podobnym problemom?A vyriesil ho?
Dakujem
Ake graficke prostredie pouzivas, tak v nom to nastav.
Mozno nestiha CPU, alebo pripadne renderovanie na GPU, preto trhavy obraz.
Podla popisu to vyzera skor na screen tearing a problem s nastavenim ovladaca GK. Nemas tiez problem pri prehravani videa? (ciara cez obraz)
chcelo by to info o laptope, ovladaci grafiky a de. (inxi -F)
tiez sa priklanam k problemu s tearingom.
Ahoj,
Teraz som si skusil prepnut Firefox do citacieho modu a ked rolujem text pomocou sipiek, tiez badam podobny problem.
Tak mam podozrenie, ze to fakt bude skor vec GK,pouzivam intel. Predtym som mal nahodene Gentoo aj tam to robilo.
Ked v prehliadaci vypnem Smooth-scrolling, tak to nebadam.Ale v Evince podobnu moznost nemam.Ked otvorim pdf v Mupdf,tak je rolovanie menej hladke.
Asi pouziva Evince nieco obdobne ako smooth-scrolling?
Co sa tyka vykonu, myslim ze toho mam dostatok (i7, 8Gb ram).

Nakoniec je riesenie pomerne jednoduche.Do konfigu treba zapisat>
Nasiel som to v tomto odkaze>
Dakujem za nakopnutie.
Keby to niekto hladal cez Google, vraj sa to vola tiez screen flickering
super.
mne to robil mint. na Intel vga tiez.
momentalne mx ma priamo v nastaveniach zakliknutie tear free.
Intel tearing je dosť známi bug. Pretože ostatné grafiky používajú variabilnú vertikálnu synchronizáciu a ten problém nemáš. Je otázka, prečo to funguje všade okrem Intelu, ale odpoveď nepoznám.
Som rád, že si to vyriešil k svojej spokojnosti.
na mx sa o tom bavilo. je to nieco v dizajne hw (bug alebo feature?), nastastie to ide jednoducho opravit
robi to aj na windows 10 tam to osetruju cez utilitu Intel Graphics Driver and System stability a nasledok je vyssia obsadenost RAM.
