[opensuse-factory] Full wayland & kmail
Hi! I wonder if somebody on this list can help: TW, KDE, full wayland session. It is _fast_ and most of the software works. There is an Emacs port to full gtk (https://github.com/masm11/emacs) and I never had such a rapidly starting Emacs in years. But kmail doesn't perform. It is really slow and often unresponsive, even if started with QT_WEBENGINE_DISABLE_WAYLAND_WORKAROUND=1 kmail & Especially the preview pane flickers and crashes every 10 seconds. This seems to be a longstanding bug - https://bugs.kde.org/show_bug.cgi?id=414955 - https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=946365 - https://forum.kde.org/viewtopic.php?f=215&t=165740 Can somebody »throw« time and effort on getting kmail fixed for wayland? Really, besides that I enjoy wayland, being so fast.

As far as I understand, the longterm goal is to have Wayland running without having a nested X-server. One major showstopper is a non working kmail. Of course we can go on with xwayland for ever, but why? But the bugs I listed above are old. The purpose of my question is to move sombody to assign a higher priority to fixing kmail on Wayland. To me KDE on TW seems really close to get Wayland ready for primetime!

I can confirm this from my experience under Arch Linux. It is definitely an upstream bug.

QT_WEBENGINE_DISABLE_WAYLAND_WORKAROUND=1 kmail &
It seems that Qt WebEngine isn't generally problematic under Wayland. Other applications using it work just fine. The only workaround I've found so far is to use XWayland, e.g. start KMail with `-platform xcb`. It is also possible to disable the "splitted" web view. The web view embedded within the stand-alone window for displaying mails seems unaffected. However, the UI still feels a little bit slow compared to X11.

So you've already found the bug where I've already commented as well.

I'm also wondering why not much KDE developers care about this bug considering that they are generally keen on improving the Wayland session. Considering that there are not that many comments under the ticket and the status is still "REPORTED" I assume they can not reproduce it. As mentioned in the bug: Other applications using Qt WebEngine combined with QSplitter work just fine by the way. So there must be some "special weirdness" on the KMail-side. Not sure how easy it is to get rid of that.
Really, besides that I enjoy wayland, being so fast.
I assume you haven't tried starting Firefox with `MOZ_ENABLE_WAYLAND=1` . And QMPlay2 and VLC don't work for me as well. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Thank you very much, very helpfull, "kmail -platform xcb" starts a stable kmail; it seems to add a Xwayland process. So I can use full wayland, with the exception of kmail. Great.
Especially the preview pane flickers and crashes every 10 seconds.

Yes, sigh.

Just tested. Works well, as far as a three minutes check can tell. Scrolling seems smother and faster.
And QMPlay2 and VLC don't work for me as well.
VLC runs smoothly. For good measure I installed QMPlay2, which runs also without complains. Ok, so it seems my old laptop without discrete GPU card may have it easier than newer machines. However, hopefully those old upstream kmail bugs get addressed. Until then: kmail -platform xcb ! Yeah!
