Re: The text display of Dolphin has a bug

Remove xf86-video-intel if installed. Try to reproduce.

Re: The text display of Dolphin has a bug

I have never installed xf86-video-intel, sorry. I only use mesa package.

and my graphics card is Mesa Intel® Xe Graphics, I wonder if the issue of xf86-video-intel is deprecated on my graphics card.

Re: The text display of Dolphin has a bug

[ 20225.605] (II) modeset(0): glamor X acceleration enabled on Mesa Intel(R) Xe Graphics (TGL GT2)

Indeed all fine on that side.
Do you get the error if you start ("killall dolphin" first)

LIBGL_ALWAYS_SOFTWARE=1 dolphin

https://docs.mesa3d.org/envvars.html

Edit: if not, try LIBGL_DRI3_DISABLE=1

Re: The text display of Dolphin has a bug

both `LIBGL_ALWAYS_SOFTWARE=1 dolphin` and `LIBGL_DRI3_DISABLE=1 dolphin` will produce the error like https://paste.c-net.org/SolomonWhadaya

Re: The text display of Dolphin has a bug

"QSG_RENDER_LOOP=basic"

There used to be an environment variable to force QSG to use the software rasterizer, but I can't find it anymore (google just yells Qt6 stuff)

Re: The text display of Dolphin has a bug

QSG_RENDER_LOOP=basic does not work either.

I was wondering if this is Dolphin's fault as other apps and system apps do not have this issue, but this issue has been occuring despite the version of Dolphin

Re: The text display of Dolphin has a bug

QMLSCENE_DEVICE=softwarecontext dolphin

And try the behavior w/ a fresh user account, just in case.
