>Description:
The problem is that I have a graphical bug when I start X. I took two photos to let you see what I have.

The system isn't frozen, I can fully interact with the system. I run i3 and everything is working behind that white thing. I just can't see anything but the mouse cursor. I can move the mouse cursor, no lag nor tearing nor anything wrong with the cursor. How I do know everything works ? The mouse cursor changes when I open the terminal and I can write comands in the terminal like to kill i3 for instance, I can try commands like the xrandr one I have to change the screen (as you can see in the photos, I use two screens) to disable or move the first screen to the right of the second screen (the cursor is the key to know if it worked). I can access in SSH to the OS. I can normally stop X.

No error message in Xorg.log but when I start X from SSH, exporting DISPLAY variable to :0, here is what the terminal says me :

-------------------------------------------------

I truncated it, it was repeating again and again the same things.

If I add the option NoAccel in xorg.conf, I won't have this glitch, it will work (but it's not an interesting workaround in my case, I need acceleration).

I can also give you dmesg

>How-To-Repeat:
Not sure but here is what I have
1. To use -current 7.99.70 and more
2. To use pkgscr current from, at least 2017/04/22
2. To use modular-xorg
3. To have an AMD GPU (Radeon R7 250)
4. To use radeon driver with acceleration (default setting)
