wl: Compoments glitching on some pages with Vivante GPU #547
Comments
Not sure if related, but we have also glitches reported with the |
@sedlalu2 Good report, with versions of involved components 👌🏼. For the same of completeness, which Wayland compositor are you using, and which version? |
And on the older device:
Not sure. Could this problem be Vivante GPU related? Drivers, mesa, etc,..? |
@sedlalu2 Thanks for the additional info. I've had Cog working well on Weston 9.x + Wayland 1.19.x on an iMX.8 based board a while ago with the Vivante proprietary driver available in the meta-freescale, but that layer adds some customizations on top of Weston 9 🤔 BTW, are you using the proprietary Vivante driver or Etnaviv? How are you building your images, Yocto? |
@sedlalu2 We are suspecting there might be a DRM/KMS driver bug, so it could be a good idea to try and run something simpler than WPE to confirm (or discard) this hypothesis. Could you try and run kmscube on your board? There is a Yocto recipe for it so I hope it shouldn't be too hard. |
@aperezdc kmscube works. Anyway, I've found out that some GL tests ( I'll try to add cog to this image and hope to see it renders pages correctly. I will let you know. |
@sedlalu2 Those are very interesting findings, thanks for letting us all know! It looks like there is definitely some driver issue with the proprietary driver (or which gets triggered only with it), but maybe We might try to make the OpenGL ES renderer of the DRM plug-in ( |
I have tried to build image:
based on Etnaviv GPU driver instead of Vivante GPU. It is still the same behavior, so cog is glitching on some pages (using still the same reference page as before. I've noticed this issue on another page as well, mostly during css animations. It doesn't matter if I use cog via |
Reported in WebKit Bugzilla, the issue is also present in the |
@aperezdc Hi, do you know if the glitching problem will be solved any soon? Thank you. |
Hi,
im using cog on stmp32mp1 device with vivante GPU.
We have a problem that on some pages components are glitching. I would say mostly during animations. For example when I open solar system example, performance is really good but componets (planets, texts,...) are glitching... Also detected this problem on another pages as well.
Same behaviour happens on my another stm32mp1 device:
