I like the design but this makes it unusable for me. I have my music collection on a permanently mounted Windows partition. If this would be the reason: No excuse, all other players I tried play my songs without a flaw: VLC, Amarok, Strawberry, Rhythmbox. Tried to use Elisa for months, so updates came through, but didn't help with the stuttering.

I had uninstalled Elisa, annoyed by the bug. No I have reinstalled it though not the flatpak but the dnf version instead. And it doesn't stutter over bluetooth! Seems to be an issue in the flatpak package. BTW the other apps I tried like Strawberry are flatpaks and work well with bluetooth.

Seems to be Flatpak-related indeed. I can reproduce it with the version on Flathub as well as the version in the KDE nightly Flatpak repo. The Fedora Flatpak version is fine, interestingly. A difference is that the Fedora Flatpak version uses the QtMultimedia backend with its own GStreamer backend, while the Flathub/Nightly builds use the LibVLC backend with its own ffmpeg backend. 2496421 6 nate 2026-02-19 22:58:33 +0000 Looks like this is a known upstream issue that's already been fixed: https://code.videolan.org/videolan/vlc-ios/-/issues/1339 Unfortunately it's only fixed in libvlc 4.0 which has been in development for ages with no clear timeline for a release. In the meantime, maybe we should switch to the QtMultimedia backend. Or just drop the Libvlc backend and its abstraction later entirely and only rely on QtMultimedia. 2496515 7 mds_foss 2026-02-20 05:06:25 +0000 Closing in favor of an existing, older bug report. *** This bug has been marked as a duplicate of bug 443184 *** 187454 2025-12-09 14:20:35 +0000 2026-02-20 05:05:18 +0000 attachment-3461514-0.html attachment-3461514-0.html text/html 1357 svoboda PCFET0NUWVBFIGh0bWw+CjxodG1sPgogIDxoZWFkPgogICAgPG1ldGEgaHR0cC1lcXVpdj0iQ29u dGVudC1UeXBlIiBjb250ZW50PSJ0ZXh0L2h0bWw7IGNoYXJzZXQ9VVRGLTgiPgogIDwvaGVhZD4K ICA8Ym9keT4KICAgIDxwPkhpIE5hdGUsPC9wPgogICAgPHA+eWVzLCBJJ20gc3RyZWFtaW5nIG92 ZXIgQmx1ZXRvb3RoIC0gd2hpY2ggd29ya3MgZmluZSB3aXRoIG90aGVyCiAgICAgIGFwcHMuPC9w PgogICAgPGRpdiBjbGFzcz0ibW96LXNpZ25hdHVyZSI+CiAgICAgIDxtZXRhIGNvbnRlbnQ9InRl eHQvaHRtbDsgY2hhcnNldD1VVEYtOCIgaHR0cC1lcXVpdj0iY29udGVudC10eXBlIj4KICAgICAg PHRpdGxlPlNpZ25hdHVyPC90aXRsZT4KICAgICAgPGJyPgogICAgICA8YnI+CiAgICA8L2Rpdj4K ICAgIDxkaXYgY2xhc3M9Im1vei1jaXRlLXByZWZpeCI+QW0gMDguMTIuMjUgdW0gMjI6Mzggc2No cmllYiBOYXRlCiAgICAgIEdyYWhhbTo8YnI+CiAgICA8L2Rpdj4KICAgIDxibG9ja3F1b3RlIHR5 cGU9ImNpdGUiCiAgICAgIGNpdGU9Im1pZDpidWctNTEyOTcyLTI3MDg1Ni1xTUhIQVUwTjdtQGh0 dHAuYnVncy5rZGUub3JnJTJGIj4KICAgICAgPHByZSB3cmFwPSIiIGNsYXNzPSJtb3otcXVvdGUt cHJlIj48YSBjbGFzcz0ibW96LXR4dC1saW5rLWZyZWV0ZXh0IiBocmVmPSJodHRwczovL2J1Z3Mu a2RlLm9yZy9zaG93X2J1Zy5jZ2k/aWQ9NTEyOTcyIj5odHRwczovL2J1Z3Mua2RlLm9yZy9zaG93 X2J1Zy5jZ2k/aWQ9NTEyOTcyPC9hPgoKTmF0ZSBHcmFoYW0gPGEgY2xhc3M9Im1vei10eHQtbGlu ay1yZmMyMzk2RSIgaHJlZj0ibWFpbHRvOm5hdGVAa2RlLm9yZyI+Jmx0O25hdGVAa2RlLm9yZyZn dDs8L2E+IGNoYW5nZWQ6CgogICAgICAgICAgIFdoYXQgICAgfFJlbW92ZWQgICAgICAgICAgICAg ICAgICAgICB8QWRkZWQKLS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0t LS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLQogICAgICAgICAgICAgICAgIENDfCAg ICAgICAgICAgICAgICAgICAgICAgICAgICB8PGEgY2xhc3M9Im1vei10eHQtbGluay1hYmJyZXZp YXRlZCIgaHJlZj0ibWFpbHRvOm5hdGVAa2RlLm9yZyI+bmF0ZUBrZGUub3JnPC9hPgoKLS0tIENv bW1lbnQgIzEgZnJvbSBOYXRlIEdyYWhhbSA8YSBjbGFzcz0ibW96LXR4dC1saW5rLXJmYzIzOTZF IiBocmVmPSJtYWlsdG86bmF0ZUBrZGUub3JnIj4mbHQ7bmF0ZUBrZGUub3JnJmd0OzwvYT4gLS0t CkFyZSB5b3UgYnkgYW55IGNoYW5jZSBzdHJlYW1pbmcgdGhlIGF1ZGlvIG92ZXIgQmx1ZXRvb3Ro PwoKPC9wcmU+CiAgICA8L2Jsb2NrcXVvdGU+CiAgPC9ib2R5Pgo8L2h0bWw+Cg== 187465 2025-12-09 19:40:41 +0000 2026-02-20 05:05:19 +0000 attachment-3557756-0.html attachment-3557756-0.html text/html 1382 svoboda PCFET0NUWVBFIGh0bWw+CjxodG1sPgogIDxoZWFkPgogICAgPG1ldGEgaHR0cC1lcXVpdj0iQ29u dGVudC1UeXBlIiBjb250ZW50PSJ0ZXh0L2h0bWw7IGNoYXJzZXQ9VVRGLTgiPgogIDwvaGVhZD4K ICA8Ym9keT4KICAgIDxwPkhpIE5hdGUsPC9wPgogICAgPHA+SSBjYW5ub3Qgc2F5IHdldGhlciBp dCB3b3JrcyB3aXRob3V0IHN0dXR0ZXIgb3ZlciB0aGUgbm90ZWJvb2sKICAgICAgc3BlYWtlcnMu IEkgaGFkIHVuaW5zdGFsbGVkIEVsaXNhLCBhbm5veWVkIGJ5IHRoZSBidWcuIE5vIEkgaGF2ZQog ICAgICByZWluc3RhbGxlZCBpdCB0aG91Z2ggbm90IHRoZSBmbGF0cGFrIGJ1dCB0aGUgZG5mIHZl cnNpb24gaW5zdGVhZC4KICAgICAgQW5kIGl0IGRvZXNuJ3Qgc3R1dHRlciBvdmVyIGJsdWV0b290 aCEgU2VlbXMgdG8gYmUgYW4gaXNzdWUgaW4gdGhlCiAgICAgIGZsYXRwYWsgcGFja2FnZS4gQlRX IHRoZSBvdGhlciBhcHBzIEkgdHJpZWQgbGlrZSBTdHJhd2JlcnJ5IGFyZQogICAgICBmbGF0cGFr cyBhbmQgd29yayB3ZWxsIHdpdGggYmx1ZXRvb3RoLjwvcD4KICAgIDxwPkNoZWVyczwvcD4KICAg IDxwPk1hcmt1c8KgwqA8L3A+CiAgICA8ZGl2IGNsYXNzPSJtb3otc2lnbmF0dXJlIj4KICAgICAg PG1ldGEgY29udGVudD0idGV4dC9odG1sOyBjaGFyc2V0PVVURi04IiBodHRwLWVxdWl2PSJjb250 ZW50LXR5cGUiPgogICAgICA8dGl0bGU+U2lnbmF0dXI8L3RpdGxlPgogICAgICA8YnI+CiAgICAg IDxicj4KICAgIDwvZGl2PgogICAgPGRpdiBjbGFzcz0ibW96LWNpdGUtcHJlZml4Ij5BbSAwOS4x Mi4yNSB1bSAxNjoyNCBzY2hyaWViIE5hdGUKICAgICAgR3JhaGFtOjxicj4KICAgIDwvZGl2Pgog ICAgPGJsb2NrcXVvdGUgdHlwZT0iY2l0ZSIKICAgICAgY2l0ZT0ibWlkOmJ1Zy01MTI5NzItMjcw ODU2LWhNMHVTR29kVnlAaHR0cC5idWdzLmtkZS5vcmclMkYiPgogICAgICA8cHJlIHdyYXA9IiIg Y2xhc3M9Im1vei1xdW90ZS1wcmUiPjxhIGNsYXNzPSJtb3otdHh0LWxpbmstZnJlZXRleHQiIGhy ZWY9Imh0dHBzOi8vYnVncy5rZGUub3JnL3Nob3dfYnVnLmNnaT9pZD01MTI5NzIiPmh0dHBzOi8v YnVncy5rZGUub3JnL3Nob3dfYnVnLmNnaT9pZD01MTI5NzI8L2E+CgotLS0gQ29tbWVudCAjMyBm cm9tIE5hdGUgR3JhaGFtIDxhIGNsYXNzPSJtb3otdHh0LWxpbmstcmZjMjM5NkUiIGhyZWY9Im1h aWx0bzpuYXRlQGtkZS5vcmciPiZsdDtuYXRlQGtkZS5vcmcmZ3Q7PC9hPiAtLS0KQW5kIGl0IGRv ZXNuJ3QgaGFwcGVuIHdoZW4gdGhlIG91dHB1dCBpcyBhIG5vbi1CbHVldG9vdGggbG9jYWwgc3Bl YWtlciBvcgpoZWFkcGhvbmVzLCByaWdodD8KCjwvcHJlPgogICAgPC9ibG9ja3F1b3RlPgogIDwv Ym9keT4KPC9odG1sPgo=
