Testing done on that branch on commit 24110c70630998dc83da23cae910a9538f54ef64.

On default Plasma OpenGL 2.0 profiles things are still laggy but a lot better.
On OpenGL 3.1 things are working much better just minor gliches on
maximzing/minimizing windows.

Firefox is still broken , frames drops , video stops etc
Cromium-browser works fine
Otter-browser does not work at all
Qupzilla/Falkon has Firefox like issues too

Things I noticed while testing Firefox or Qupzilla..
Once these start acting up it does affect the whole Desktop,
for some secons scrolling lags , mouse is slow , etc.
Once these are closed the Desktop start working again after few seconds.


Do you want me to test any mesa/xorg-server/drivers git/branches too ?

If so just let me know.
