Please always attach files to the bug report not some third party site. Third parties do lose data over time.
Comment 4 Harald Sitter 2021-09-02 12:45:14 UTC 
What's curious is that it works correctly for the processor label, so whatever is wrong must already be wonky in the string coming out of opengl.

Please also get the output of
`glxinfo |grep -i 'opengl renderer'`

(though admittedly I'm not sure we'll see what's wrong from just that).

The output from glxinfo is fine:

$ glxinfo |grep -i 'opengl renderer'
OpenGL renderer string: Mesa DRI Mobile Intel® GM45 Express Chipset (CTG)

That is why i thought something messed up the encoding.

Thanks. Your hunch was correct, I see what's wrong now.

Git commit 5ab22ea18fa05482e233a2b375eb83ad4d8a932c by Harald Sitter.
Committed on 03/09/2021 at 09:34.
Pushed by sitter into branch 'master'.

construct GL renderer string from unicode

as it turns out we wrongly assumed the value would be latin1 when indeed
the output may be unicode (e.g. include registered trademark symbols)
