same graphical glitches on qutebrowser so I think it affects the QtWebEngine

6

That was what happened the first time as well.

7

any idea how it got fixed the first time ? I still have this problem

8

I don’t know. Hopefully, one of our devs will weigh in on this.

There was an update in Rock to address it from an upstream patch if I recall correctly.

sudo dnf dsync --refresh --allowerasing
10

every day I update my system with that command sudo dnf clean all ; dnf clean all ; dnf repolist ; sudo dnf distro-sync --allowerasing

I am up to date and the problem is back (came back around the time when I filed the github issue)

11

Does the issue occur with X11?

12

yea same thing on X11

13

This may help with both:

It also includes upstreams. @bero will probably need to patch Qt again.

14

setting env variable QTWEBENGINE_FORCE_USE_GBM to 0 works

maybe we should set that var to zero by default in OpenMandriva ? Not many people would complain about not having gpu acceleration in that one welcome script but they will complain if the thing straight up doesn’t work

related bug report in Qt Loading...

15

This will be something for @rugyada to consider.

16

Uhm… I mostly take care of the GUI, and the scripts (with @bero 's help).
If it’s something related to the engine or the Qt stuff under the hood that’s not exactly my field.

We could set it to zero in the context of om-welcome for sure, no heavy rendering involved there… But setting it globally would slow down falkon, qutebrowser etc. significantly.

Would be nice to know what conditions are needed to trigger this, given we see a few complaints about this while it seems to work as expected for most.

No issues here with a Radeon RX 550 or an onboard Intel Iris Xe.

The card I had issues with was an actual ATi HD 4250.

yea setting it to zero in htmlscript/om-welcome would probably be enough

I tried the live USB on my GPD Win 4 (Ryzen 7 6800U) and I got no glitches, that same USB stick got glitches on my RX 9070XT

I sent a pull request to om-welcome force CPU rendering (fix graphical glitches on AMD GPUs) by vulonkaaz · Pull Request #73 · OpenMandrivaSoftware/om-welcome · GitHub

it fixes the graphical glitches by setting the QTWEBENGINE_FORCE_USE_GBM var in om-welcome’s launch scripts
