Bug ID: 47431
Summary: Steam and wineserver too high CPU usage
Product: Wine
Version: unspecified
Hardware: x86
URL: https://steamcdn-a.akamaihd.net/client/installer/Steam
Setup.exe
OS: Linux
Status: NEW
Keywords: regression
Severity: normal

terminal output
Steam.exe and the wineserver processes consume much more cpu power than they
used to, even when Steam is idling.
On my rather old system equipped with a dual-core AMD processor, htop shows
that Steam.exe constantly consumes 35-40% cpu power, wineserver 55-60%. This
was tested with the game library page opened and while Steam was idling. Before
the regression: Steam.exe: 12-15%, wineserver: 5-6 %.
It's not just the Steam client that reacts more slowly to mouse input, e.g.
when browsing through the list of installed games, but every game started
inside Steam has a noticeable performance hit.

winex11.drv: Use generic EnumDisplayMonitors.
The problem happens both in Wine's fullscreen and virtual desktop mode. I have
a single monitor setup and using XFCE on Arch Linux.
