[UI] Wayland Meta Thread

[itsmattkc]

We don't currently have the means to properly support Wayland and there appear to be several issues when using Olive natively on Wayland rather than X11 or XWayland. To prevent clogging up the issue tracker, I'm making this thread as a general list of known issues on Wayland that people can post in and add to instead. If you're an expert with Wayland, feel free to contribute pull requests to solve any of these issues.

• Viewer/render issues. Textures will show other parts of the desktop rather than the video being rendered. Possibly an OpenGL context issue. ([RENDER] Wayland: Window below is visible in the preview rendering (+ artifacts and flickering) #1507)
• Action search does not appear to respond to keyboard input. ([UI] [Wayland only] Action search not working #1629)

If you find other Wayland-exclusive issues, comment here and they will be added to this main post.

Start a “Discussions” thread and merge there?

@elsandosgrande Could you please check whether you are experiencing #1629 on Gnome Wayland, too?

[mara004]

Maybe we could clarify point 1 a little: It's not that the video to be viewed would be completely invisible, only the background flickers and is (half-)transparent, but the video itself is rendered correctly. Maybe that was not clear enough from my screenshots and description.

[mara004]

I just tested ae3393f, but it didn't fix #1507.

[mara004]

The following is not a real issue since it currently does not impact the user, but maybe it's interesting information anyway:
When using Olive as Wayland client, I frequently get this warning on the command-line:

[WARNING] setGrabPopup called with a parent, QtWaylandClient::QWaylandXdgSurface(0x55a5d8f499a0) which does not match the current topmost grabbing popup, QtWaylandClient::QWaylandXdgSurface(0x55a5debc3470) According to the xdg-shell protocol, this is not allowed. The wayland QPA plugin is currently handling it by setting the parent to the topmost grabbing popup. Note, however, that this may cause positioning errors and popups closing unxpectedly because xdg-shell mandate that child popups close before parents ((null):0)

For instance, this message shows up when triggering the pop-up explaining that you can't export an empty sequence. Maybe (probably?) it's with all olive pop-ups, I haven't checked.

@itsmattkc , I've got crash on startup.
here is the DEBUG output.

[mara004]

@HarshilPatel007 Yes. This is because you are using the AppImage, which does not ship the Wayland platform plugin. I think it's a known packaging issue (#1487). If you build Olive from source, you'll be able to run the program as native Wayland instance (with a few usability issues, though).

@mara004 , tried to build. but, got errors..!!!!

@HarshilPatel007 I ran into that issue a few months back myself and a workaround was discovered: #1590

Edit

Quick question: Which version of GCC are you using?

@elsandosgrande , I'm using gcc (GCC) 11.1.0

edit:
adding -Wno-stringop-overflow after -Wextra in CMakeLists.txt solved the problem. 👍 thanks.

[HarshilPatel007]

@mara004 @itsmattkc @elsandosgrande ,
got error/crash on startup..!!!!
@mara004 I've compiled from source as you've suggested. but, now got so much errors than previous AppImage.

Maybe try ./olive-editor -platform wayland. Apparently you are running a cutting-edge distribution with unusual configuration?

The strange thing is that the program should actually select Wayland automatically, but for you it doesn't. Did you build with the Qt/Wayland development libraries installed?
Moreover, it seems that XWayland is completely disabled on your system?

I just built Olive on current Neon User with Plasma Wayland and cannot reproduce your problems.
