Created attachment 94835 [details] Drawing with mouse on what used to be firefox screen Hello. I am running Xorg 1.15 with radeon(r600g) and intel gpus. I want to use xrandr's setprovideroutputsource feature, but its unusable since there are too many glitches. Background: I have a laptop with MUXed Intel + AMD setup. Sadly, intel is connected only to vga and lvds, while AMD is connected to vga, lvds and HDMI. So I can't use hdmi without restarting X on AMD card. What I see, is that screen parts are not updated, unless I will move mouse pointer over it. So there are problems with redraw, nothing redraws unless forced with mouse pointer. Sometimes I can draw pictures with my mouse(see picture). glxgers works fine. lspci | grep -i vga ~ @laptop-arch 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12) 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

Before starting the window manager: xrandr --setprovideroutputsource radeon Intel xrandr --setprovideroffloadsink radeon Intel xrandr --output LVDS2 --mode 1366x768 --pos 0x312 --output HDMI-1-0 --mode 1920x1080 --pos 1366x0 Generally the output is working: lvds on the left and hdmi output on the right. But: I see the same effect that the hdmi picture is not redrawn correctly (I will attach a picture). The lvds screen works properly. What both of us have in common: - same discrete graphics card: Mobility Radeon HD 5650/5750 / 6530M/6550M - same window manager: i3wm - same effect Have you tried to use another window manager?
Hello, I haven't, I only tried with i3wm. This is an interesting point, afaik modern DE's utilize OpenGL capabilities and I belive OpenGL worked fine with setprovideroutputsource(not sure about tearing though). I will try to recheck it at the weekend, what would you recommend for it?

Hello, I do not have a recommendation because I do not know enough about this stuff. Maybe this comment is helpful? "i3 does not properly implement double buffering hence tearing or flickering may occur. In case of problems, try using a composite manager." (from https://wiki.archlinux.org/index.php/i3) I tried the composite manager compton, but that didn't make a difference. Additional info: Sometimes the radeon driver will crash/reset and system will hang for some seconds if I move the mouse the the hdmi output. In this case the hdmi screen will not change its picture for this power cycle. Do you think I should create a new bug ticket for this?

Somehow I "solved" (?) the issue using compton and different parameters. I accidentally found this topic: https://bbs.archlinux.org/viewtopic.php?id=161403 They suggest to use compton this way: compton --backend glx --paint-on-overlay --vsync opengl-swc Now it works. But: - the background picture is not working (I will add an screenshot). - the mouse pointer flickers sporadicly I do not know why compton solves the issue. What do you think is the reason? Does anyone options for fine tuning?

I have the same hardware (ATI 5650 Mobile + Intel Ironlake, muxed) and the same problem. I also use i3 but I tried KDE with KWin and it had the same problems as the solution using the above compton command. The problem is also not limited to this hardware. A friend has an Ivy Bridge + Nvidia 640M (or was it 540?) (muxless) that shows exactly the same symptoms.
