Julien,
This version is no longer in Buster - kernel version is now 4.19 and
libdrm-radeon1 is now at 2.4.97 rather than 2.4.90 . On an AMD E-300
with Radeon, I cannot reproduce this bug.
Hardware here is a Lenovo x121e which reports AMD/ATI Wrestler [Radeon HD 6310]
Is this still a problem for you?
