GPU acceleration break inline maps in brave, vivaldi and chromium

General system Applications
1

I am still in my test phase for chromium based browsers. Yesterday I realized that brave is not showing the inline maps of the komoot.de webpage. When I turn off GPU acceleration it works. I opened an issue for it with screenshots:

After that I tested vivaldi and chromium and they both behave the same way.

Does anybody else notice that as well?

No problem with vivaldi, but as a side note I am using quad9 dns server.

You have “Use graphics acceleration when available” enabled?

Which GPU do you have? Can you share inxi -G
I have AMD Radeon RX 6650 XT

Can you also share output of brave://gpu? Specifically the section at the top of the page showing hardware accelearation.

Here is mine:

  • Video Decode: Hardware accelerated
  • Video Encode: Software only. Hardware acceleration disabled
  • Vulkan: Enabled
  • WebGL: Hardware accelerated
  • WebGL2: Hardware accelerated

For vivaldi this is:

"Use Hardware Acceleration when enabled"

and vivaldi://gpu

Hardware acceleration is enabled.
The inxi.

This is an integrated GPU in an Ryzen 7000 processor. Correct?

Your vivaldi says: Vulkan: Disabled
Mine says: Vulkan: Enabled

Can you test with vulkan? What does vulkaninfo say on your system?
You can enable vulkan in vivaldi://flags

Cpu is a ryzen 5 7600 with IGP , with vulkan enabled there is no problem .

ok. thank you for testing.
Then the only difference remaining is the integrated graphics vs. separate graphics card.

I found the issue. My ~/.config/brave-flags.conf contained

--enable-features=DefaultANGLEVulkan,VaapiIgnoreDriverChecks,Vulkan,VulkanFromANGLE

the feature DefaultANGLEVulkan was the issue. Without it the komoot maps are displayed fine. Video playback is still accelerated to a point that I do not see a difference in CPU consumption with or without this feature. But nevertheless, brave://gpu now says Vulkan: Disabled.
