Steam login window is empty with dri3. Window is functional. I can write my password and when I press enter I can login to steam. After that everything is normal. With dri2 bug is not present.

Is there anything more needed?
If you want more tests or you want me to redo previous tests or if you are unsure about results, I'm happy to help.
This could be due to a fundamental incompatibility between DRI3 and EXA (as it is used by the radeon driver). That incompatibility is the reason for the radeon(4) manpage saying:
Note: DRI3 may not work correctly in all cases with EXA, enable at your own risk.
You can try glamor, but I'm not sure it can work with your GPU.

Yea I think it can't /var/log/Xorg.0.log
>glamor requires at least 128 instructions (64 reported)
Is is worth to try to fix DRI3 and EXA for this driver or is it better to stick to DRI2?

I'd say the latter.
