Solved Broken text on tabs

DoctorG

@zesko The browser UI is created by HTML, CSS and JS, comparable to a webpage.

@doctorg I see, that is why ...

@zesko said in Bad reading inactive tabs in Gnome 42 Wayland:

I disabled --enable-gpu-rasterization in the flags

Just being curious: you had enabled the flag before on your own for optimisation or perhaps it was set by Chromium core's GPU detection?

Zesko

@doctorg

It was enabled by default after installation of Vivaldi. Like Chromium.

I checked any websites with 3D simulation, I do not notice any issue.

Good evening,
I do the exact same issue. I tought first the problem came from my laptop as I updated it to Ubuntu 22.04 - so I did what I wanted to do for a long time and switch to Fedora.
But the problem is still there, and that's pretty annoying.
Im not as advanced as you all and I'm not sure to have understood : waiting for a fixing update is the only thing we can do ?
Thanks

See attached screen shot. The tab looks like it's duplicating the text over top of itself and makes it illegible.

If I hover over a tab with this problem the text is temporarily fixed.
It also does not happen on an active tab.

@exist2resist Seems all fine here [but i'm only using a VM, not on-metal].

Suggestions:

can you verify in a clean test profile [eg, via vivaldi-stable --profile-directory="NewTestProfile" in terminal]?
Fedora WS session default is Wayland; have you retested in X11?
still in Wayland, try launching your V as a full-W app, not its default Xwayland app mode, by vivaldi-stable --enable-features=UseOzonePlatform --ozone-platform=wayland?
try launching your V from terminal with either of these switches appended: --disable-gpu or --disable-gpu-compositing?

Have exact same problem on latest Manjaro with 5.2. Somehow it fixes itself for a few minutes depending on mouse focus, new tabs created / existing tabs closed.

vaygr

@guigirl I'm on X11, and neither of profile / gpu / gpu comp suggestions fixed anything.

vaygr

Reverting to 5.1 fixes the issue.

Aha, a clue!

You can fix it by disabling gpu rasterization in flags temporarily

disabling gpu rasterization in flags

Thank you. I confirm that disabling GPU rasterization fixes the issue for now ...

vivaldi://flags

GPU rasterization -> Disabled

@vaygr Downgrade is not advised by Vivaldi, such will crap browser data and cause strange effects.

DoctorG

Same issue here, Arch with Gnome on Wayland with Iris Xe graphics.

It worked perfectly before 5.2.

I do not use Wayland, my default is xorg.
Your suggestions did not help anything still getting the same issue.
Was fine on Fedora 35 prior to upgrading.

Thanks

You are all using Intel Xe Graphics and you have all moved to a newer kernel, newer mesa version etc. Newer is not always better.

you can do one of the following:

try with an older kernel
try with Vulkan instead of GL (assuming you have everything vulkan necessary)

$ vivaldi-stable  --use-vulkan --enable-features=Vulkan

try disabling hardware acceleration or parts as instructed
try living with a basic Vivaldi (without its UI) with

$ vivaldi-stable --disable-vivaldi

try Vivaldi Snapshot (5.3) to see if it is also affected
report the bug to the bugtracker
wait for 5.3 hoping/in case it is not affected
use another browser which is not affected

There is no world where I run a modern browser without hardware acceleration, so that is not an option.
Do you have a link to 5.3 snapshot for rpm package?
