Comment 43 for bug 1861554

Old algorithm which were included up to kernel 4.15.0-54-generic seems to work no problems for long time until there has been reported problem with Radeon X1600 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1791312
It seems that when algorithm has been changed it broke image for multiple different card types which were working before.
If it is not possible to create solution which would work correctly on all cards there should be at least added some parameter for graphics configuration which would allow to switch between old and new settings manually.
Something like:
 TearFree: auto
  supported: off, on, auto

I would suggest to add 3 modes which would choose between auto, old algorithm and new algorithm.
In auto mode it would select new algorithm for Radeon X1600 and old for other cards. At least it is confirmed that old should be used with HD3450 and HD3650. In any case if auto would work incorrectly user could easily switch manually.

This is really problematic for laptops since you can't just simply replace card with another cheap card which has better linux support. Many older laptops which are running older Windows releases could be switched to Linux instead of Windows 10. Currently it does not work correctly on any recent linux distros.
