Above fullscreen about glava

[RaitaroH]

Just to be clear: if I watch a video in fullscreen in browser or media player, it would be nice if glava wold be able to stay above those as well.

#request addxwinstate "above" will accomplish this, but it means it will be above all windows, not just when a window is fullscreen. You should still be able to click through it if it's a desktop window, otherwise make sure #request setclickthrough true is set.

I did that before opening the issue, both in rc and kwin files. "below" is quoted too. Glava just doens't stay above fullscreens, nor does anything else that is "above". I just thought "above" was for above windows that are not fullscreen or something like that. Even if I set the above with kwin, wmctrl or in this case the config file. This is how it is in KDE Neon 5.13.5 (ubuntu 18.04).

EDIT: I can post my configs if that helps.

@RaitaroH I'll spin up my KDE container later today and try to find something that works. It is really frustrating that the WM routinely misbehaves with EWMH hints and window types, perhaps a collection of these problems I have had with GLava should make their way into a KWin issue.

[jarcode-foss]

Closing due to technical reasons making this impossible to implement elegantly, see my related comment in another issue.

[jarcode-foss]

It was occurred to me that override_redirect may allow me to map GLava's window without the window manager even knowing, so there's still a chance that I could get this issue fixed.

[jarcode-foss]

Alright, there's a special "unmanaged" window type that has been added in the above commit that may be able to get what you want, see the added comments in rc.glsl:

/*
   ...
   
   Alternatively, you can set this value to "!", which will cause
   the window to be unmanaged. If this is set, then `addxwinstate`
   will do nothing, but you can use "!+" and "!-" to stack on top
   or below other windows.
*/

So #request setxwintype "!+" will cause GLava to be ignored by the WM and will be above all other windows when created -- whether it stays there depends on the WM. If it's not staying, then #request setforceraised true will work (albeit with intervals) here without screwing with window focus.

"!+" windows also appear to display above fullscreen windows*, although some applications that also use override_redirect for fullscreen may have strange interactions.

Another thing worth noting is that this could allow GLava to work on the desktop with i3 (and i3-gaps) using "!-", see #6.

* not tested on KDE

@wacossusca34 The windows stays above fullscreen... but it freezes. So is basically an unfocused overlay now instead of actually visualizing anything. I tried ! !+ !- with force raised and not, both in kwin and rc files and I couldn't get this to work. I am on nviida prop drivers, perhaps that could have something to do with it.

[jarcode-foss]

@RaitaroH oh, I forgot to mention that you will also need to set #request setfullscreencheck false. This is supposed to prevent GLava from eating resources that fullscreen applications would normally use by halting the rendering, but in your case you will want it disabled.

[RaitaroH]

@wacossusca34 I added that too... still freezes.

Also, I do remember glava working without options... but now I get a crash.

@RaitaroH crashes need to be debugged with make BUILD=debug and gdb glava. Posting your rc.glsl (and any other changed files) will help.

Ok so...

I did also build with debug but, glava crashes on start:

GLava (glava) v1.5.1-11-g353c3bd (stable, unix/fhs)
I am extremely sure I tried setforcedraised and setfullscreencheck to true before... Not sure what changed since #65 (comment)

Now I have in my kwin file looks like this. Thank you by the way.
EDIT: no minimize funny business either. So KDE stacking issues are gone for me.

Your GDB output is the default gdb startup banner, you have not yet started the program inside the debugger

[RaitaroH]

@coderobe ups. I fixed it.

[kirolos-mater]

Watching video,
But glava will stay below...
It should be above.

Don't use "glava --desktop" command, only "glava" & #request setxwintype "dock"
