--- Comment #66 from Gediminas Jakutis  ---
attachment 48503 seems to fix all the problems with CS:GO in "fullscreen
windowed" mode and returns the performance back to the same level it was before 
4c4552c5a1910a9d5adf8eccff0ac62d89ffe376

Seems to fix problems with Age of Wonders III, too. Albeit, while closing AoW3
when ran in Borderless mode, it generates:

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  155 (GLX)
  Minor opcode of failed request:  5 (X_GLXMakeCurrent)
  Serial number of failed request:  2082
  Current serial number in output stream:  2082
