The AppImage is currently using the QWebEngine. This requires a functioning OpenGL support. Which graphics card and drivers do you use?

Maik

I am using the newest nvidia driver.
I have Hybrid Grafics.
The Error appears on both graficcards.
But on Nvidia grafics the error is different.

The Log on Nvidia grafics:

When I start Digikam with the Nvidia grafics (940MX)

Everything starts normaly

One Question about the fault.
Is this a bug or is it fault from my installation of the Intel 620 Grapicscard?
Because outside so much people have a Intel 620.

Sorry for the easy question.

I will help to improve Digikam.
Martin

Yes, it depends on the graphics card and driver. No problems at all here with AMD and Radeon. The activation of QWebEngine is a test in the beta version to assess how QWebEngine works. We can switch back to QWebkit for the AppImage at any time. But the future will be QWebEngine. Some distributions have already removed programs that still use QWebkit from the standard installation.

Does the Chromium browser work with active hardware acceleration when you open pages like Google Maps and quickly zoom in and out?

Maik

No problem here too with NVidia video cards tested on desktop and laptop computers.

QtWebKit is really problematic with security issues, even if code maintenance continue (until when, we don't know). The plans are clear : use it for MacOS and Linux by default for 7.0.0. Only Windows cross compiled version will use QtWebkit, as QtWebEngine compile only with MSVC. We have a MSVC compilation workflow working fine on the CI but for the deployement, compilation do not pass yet.

I have purchased a laptop which only has Intel based GPU for Linux compatibility and so far it never failed. It claims to support up to OpenGL 4.6 and Intel is known for their lower performance but bug free drivers. What bugs me is, Mac Mini 2009 including proprietary closed source  (nvidia 340)  driver and featuring pretty outdated nvidia 9400 can launch the appimage.

I am all for new frameworks but it seems there is a QA issue with the new web rendering library.

On googling you can find this hint that libglvnd should not be installed because it breaks Qt ... just one try ...

Maik

I moved to SUSE Tumbleweed from Manjaro, it does have  libglvnd installed (default I think)
 zypper search libglvnd

i | libglvnd             | The GL Vendor-Neutral Dispatch library | package

and yet Digikam appimage launches fine. (I moved the exact same file). I can setup a Manjaro VM and do further testing.

output of App Image launch both in stable and unstable

I installed a fresh Manjaro to a Virtualbox VM (using VMSVGA, the kernel supported gpu) and tried to launch 7.2 beta 1 appimage. Didn't work. I also switched to bleeding edge "unstable" Manjaro to make sure if update fixes anything. No luck. Again, I really like Digikam and can help testing no matter what.

I tried to remove that library. It removes almost the entire KDE from OS :-) Everything depends on it, at least on Manjaro current.

Hello guys, I'm also suffering from this issue on F32 and here and I tried a workaround given here: https://github.com/probonopd/linuxdeployqt/issues/331#issuecomment-441544377 which removes the bundled libxcb-dri3 library and it works.

Tried with 7.2.0-beta1 as well as digikam-7.2.0-beta2-20201122T121503.

I don't know much about appimage but it looks like the bundled library is outdated or just wrong and it works well with the system-wide installed libxcb-1.13.1-4.fc32.

To confirm Lukáš Doktors posting:
With digikam AppImage 7.1.0 on F33 (and system-provided libxcb-1.13.1-5.fc33) the following helps:

./digikam-7.1.0-x86-64_426bf2da2f9688e7e69b5708f65a73d4.appimage  --appimage-extract
find squashfs-root/ -iname '*libxcb-dri3*' -delete
./squashfs-root/AppRun

It seems that libxcb-dri3 should either not be included in the AppImage or at least in a current version.
