I wonder if anyone else has seen this bug: sometimes when the screen unblanks the colors are all wrong.
Examples of wrong colors:
normal colors for comparison:
apologies for the poor quality - pictures where taken with a mobile phone.
Also, they were too big to attach here, and I didn't want to resize them and make them even crappier.
Details - this workstation runs FreeBSD 11.3-release:
kernel
the drm packages are
the graphics card is a MSI R5 230 2GD3H LP, which is identified like this
when the bug appears the screen is unusable (too hard to read text), but if I wait until the screen blanks again and then press a key to unblank it the normal colors are back.
I see this bug on two different machines, connected to two different monitors (the other machine have a MSI Radeon R5 230 1GB DDR3 graphics card) so I don't think it is a hardware bug. It has happened for a while, both on FreeBSD 11.2 and 11.3, with several versions of drm-kmod.
Also:
- no messages related to this in logs
- if I take a screenshot when the wrong colors are showing, the screenshot shows normal colors
I tried looking for bugs related to this, but couldn't find any.
