Bug ID: 442132 Summary: 4k videos are choppy on Wayland Product: Haruna Version: 0.7.0 Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: generic Assignee: georgefb...@gmail.com Reporter: herzensch...@gmail.com Target Milestone: --- SUMMARY 4K videos on X11 play perfectly fluid, Full HD videos on Wayland play perfectly well too, but 4K videos on Wayland get choppy, especially when maximized/fullscreen. Forcing hwdec with vaapi improves this a bit, but it's still choppy. This was tested on both Plasma Wayland and GNOME Wayland. STEPS TO REPRODUCE 1. Download Big Buck Bunny in Full HD and 4K (http://bbb3d.renderfarming.net/download.html) 2. Compare how fluidly Full HD plays on Haruna compared to 4K 3. Compare how fluidly 4K plays on Haruna compared to VLC or MPV SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20210904 KDE Plasma Version: 5.22.5 KDE Frameworks Version: 5.85.0 Qt Version: 5.15.2 Kernel Version: 5.13.13-1-default (64-bit) Graphics Platform: Wayland Processors: 4 × Intel® Core™ i7-5500U CPU @ 2.40GHz Memory: 7.7 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 5500 ADDITIONAL INFORMATION # FFMPEG ffmpeg version 4.4 Copyright (c) 2000-2021 the FFmpeg developers built with gcc 11 (SUSE Linux) configuration: --prefix=/usr --libdir=/usr/lib64 --shlibdir=/usr/lib64 --incdir=/usr/include/ffmpeg --extra-cflags='-O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector-strong -funwind-tables -fasynchronous-unwind-tables -fstack-clash-protection -Werror=return-type -flto=auto -ffat-lto-objects -g' --optflags='-O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector-strong -funwind-tables -fasynchronous-unwind-tables -fstack-clash-protection -Werror=return-type -flto=auto -ffat-lto-objects -g' --disable-htmlpages --enable-pic --disable-stripping --enable-shared --disable-static --enable-gpl --enable-version3 --enable-libsmbclient --disable-openssl --enable-avresample --enable-gnutls --enable-ladspa --enable-vulkan --enable-libaom --enable-libass --enable-libbluray --enable-libbs2b --enable-libcelt --enable-libcdio --enable-libcodec2 --enable-libdav1d --enable-libdc1394 --enable-libdrm --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgsm --enable-libjack --enable-libmp3lame --enable-libmysofa --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librav1e --enable-librubberband --enable-libsvtav1 --enable-libsoxr --enable-libspeex --enable-libssh --enable-libsrt --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvmaf --enable-libvorbis --enable-libv4l2 --enable-libvpx --enable-libwebp --enable-libxml2 --enable-libzimg --enable-libzmq --enable-libzvbi --enable-lto --enable-lv2 --enable-libmfx --enable-vaapi --enable-vdpau --enable-version3 --enable-libfdk-aac-dlopen --enable-nonfree --enable-libvo-amrwbenc --enable-libx264 --enable-libx265 --enable-librtmp --enable-libxvid libavutil 56. 70.100 / 56. 70.100 libavcodec 58.134.100 / 58.134.100 libavformat 58. 76.100 / 58. 76.100 libavdevice 58. 13.100 / 58. 13.100 libavfilter 7.110.100 / 7.110.100 libavresample 4. 0. 0 / 4. 0. 0 libswscale 5. 9.100 / 5. 9.100 libswresample 3. 9.100 / 3. 9.100 libpostproc 55. 9.100 / 55. 9.100 # libmpv 0.33.1+git.20210630T163736.f2afae55e9-1.2 -- You are receiving this mail because: You are watching all bug changes.
