[-- Attachment #1 --] Hello, running CURRENT (FreeBSD 15.0-PRERELEASE #3 master-n279925-393356f25fb8: Thu Aug 28 06:53:41 CEST 2025 amd64) on a moderat modern hardware (AMD based), I whitness some very strange and nasty performance issues with the usage of certain "day-to -day" applications, like Firefox, LibreWolf, mplayer. CPU is a current AMD Ryzen (no 3D cache!), 96 GB RAM, GPU is a nVida RX 5060 - with recent nvidia-driver-580.76.05.1500063 driver version due to issues with the 570 series in ports tree. X11 window manager is x11-wm/windowmaker. All ports are custom compiled and has been recently recompiled - these details just for the record. The phenomenon is when starting Firefox and/or Librewolf, these programs are almost unusable. Clicking on menus produce drop down artefacts in the shape of the drop-down-menu when moving the window. Content of the interior does not change and is frozen and/or doesn't get refreshed. After several long minutes this misbehaviour seems to mitigate and the program seems mor responsive. When it comes to video streams, like youtube, the mess is back: streams are slowed down a way its like a torture watching them. Same with videos in mplayer: playing a video we made a couple of years ago with Blender (.mkv, .avi) are in slow motion. From time to time I try my best with warzone2100 - the game also indicates sometimes while in game a sudden jumpy behaviour or at the beginning. It seems erratic when and how such "jumpiness" occurs. While those applications show up harsh and serious performance problems, the OS itself and even the X11 windowmaker window system do not indicate any flaw in performance penalties, which surprises me. So, I susepct something wrong with either the video subsystem (as mentioned initially, the in-ports-tree driver nvidia 570 shows some similar problems which could be mitigated by using the most recent one provided by nvidia, version 580.76.05). I tried to recompile every single port from scratch due to suspect some ABI issues somewhere since some critical changes in FreeBSD's core, but this approach didn't help much. Does anybody else have such problems on the recent CURRENT system and is this well-known (and so the hope for a solution does not die early) or is this problem sticky with me alone? Thanks for the patience, oh -- A FreeBSD user [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- iHUEARYKAB0WIQRQheDybVktG5eW/1Kxzvs8OqokrwUCaLBvTwAKCRCxzvs8Oqok r+g6AQCVLOpZJua7Rz8dMZzNPSoueCRsfuaqgf6tSBXKWA9lGwEAlCkNGo3RfvNP yrahCvhKq8LnZh8t+Umz1oT7ndn5Pgo= =7L5Z -----END PGP SIGNATURE-----home | help
