[kwin] [Bug 409490] Recording desktop video isn't possible with compositing disabled
https://bugs.kde.org/show_bug.cgi?id=409490 --- Comment #14 from Nick Stefanov --- I mainly use Simpe Screen Recording and OBS. The games with the problem are Wine DXVK games. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=409490 --- Comment #13 from Martin Flöser --- Yes of course all of them. There is no screen recording interface on X11. So what do the applications do? None of them created a performant screen recording interface. So they all abuse functionality which is not meant this way. I just checked how recordmydesktop records: it uses either GetImage or ShmGetImage. You are playing a game which is probably OpenGL rendered using direct rendering? I do hope for you that the game uses direct rendering to bypass the X server and render directly to the GPU. In no sane world ShmGetImage will return back the image to you. The closest X11 has to a screen recording interface is the composite extension which is not used by recordmydesktop. Sorry, but there is just no sane way to record on X11. On Wayland we created this by explicitly looking at what's wrong on X11 and added it directly in the compositor in a way that it doesn't need to read back to memory and provide a performance penalty. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=409490 --- Comment #12 from Nick Stefanov --- All of them? I don't think this is right. When something have a problem with all of the available software I'm sure the problem isn't in the other software. If a web site is opening correctly with all browsers but has problems with Pale Moon, where is the problem? In the site? I don't think so. When I come upon a game with this problem I'll try it with --no-wm-check command. Thank you. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=409490 --- Comment #11 from Martin Flöser --- @Nick: Did you try recordmydesktop with the --no-wm-check command line option? Are you recording the complete desktop or do you use the --windowid command line switch to just capture the game? I'm now in front of a real keyboard and explain why I am so sure that this is not a bug in our software. I am aware of the heuristics for example recordmydesktop does - such heuristics are a bad idea to start with. How does one want to do one heuristic to cover KWin composited and non-composited? And even if, is that the only contributing factor? Certainly not, in Plasma we have several untypical components which break such heuristics. For example the task manager is an additional compositor (which is totally fine and in-spec) and the main difference to other desktop environments is that Plasma doesn't render into the root window. This can be contributing factors to breaking screen recorders. But everything we do is totally fine and totally in compliance with the X protocol and we have done so for years. If screen recorders cannot handle this, it's their bug and not ours. -- You are receiving this mail because: You are watching all bug changes.

The reporter is having an issue that only manifests when using Plasma with KWin and it isn't fixed yet. Maybe the root cause isn't KWin's fault, but some investigation needs to be done to determine where the issue might lie.

I think it's premature to give up and say "just use Wayland instead" especially because your exact use case (games running in WINE) doesn't work on Wayland. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=409490 --- Comment #4 from Nate Graham --- I've used SimpleScreenRecorder to successfully take a screen recording of the game Endless Sky while compositing was disabled. If it's game-specific, that seems to point to an issue with how the game itself interacts with the rendering pipeline. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=409490 --- Comment #3 from Nick Stefanov --- I recorded over 250 Wine game videos with X11: https://www.youtube.com/channel/UCm21eK86ZmD0FQoNPGqvKlw/videos?view=0=dd_id=0 They will not run with Wayland. As I alredy wrote I tested every single software I found googling around and the result is the same. It depends on the game though.

https://bugs.kde.org/show_bug.cgi?id=409490 --- Comment #2 from Martin Flöser --- This is a problem of the recorder you use. If compositing is disabled KWin is not involved at all. Please be aware that recording adds a huge lag no matter whether compositing is enabled or not. X11 is not designed for such use cases and performs extremely bad for screen recording. I recommend to use Wayland instead. -- You are receiving this mail because: You are watching all bug changes.
