Hi,
I'm using the integrated Intel HD Graphics with "Intel
8xx/9xx/G3x/G4x/HD Graphics" driver from mainline linux-4.6.0.
00:02.0 VGA compatible controller: Intel Corporation Device 191b (rev 06)
vendor: 8086 ("Intel Corporation"), device: 191b ("HD Graphics 530"),
class: 03 ("Display controller")
Is there a way to build urxvt without hardware acceleration but
transparency turned on and check if the problem still persists?
Torsten
