Android AVDs not working with hardware acceleration

4.9.0-2-amd64 #1 SMP Debian 4.9.18-1 (2017-03-30) x86_64 GNU/Linux
Android Studio 2.3.3

When I try to run an AVD with hardware acceleration I get this error:

emulator -avd n5 -verbose
...
emulator: Initializing hardware OpenGLES emulation support
libGL error: unable to load driver: i965_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: i965
libGL error: unable to load driver: i965_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: i965
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  155 (GLX)
...

So then I tried to use my system libraries ( running with -use-system-libs) and it started but the display small but it does accept input:

enter image description here

EDIT 1: The the input is borked still but I think I know why the screen is so small, I have a high density display. Perhaps there is a way to compensate for this?

EDIT 2: It does accept input (there was just some lag). So the problem is just the small screen. I've tried a variety of AVD images but all have the same issue.

I'm using a 15" 4k display, so disabling scaling globally was not an option for me. Instead I was looking to disable scaling for the avd only.

Unfortunately I was unable to add QT_SCREEN_SCALE_FACTORS=1 as a parameter before the emulator command in android studio settings.

What I ended up doing was renaming {$ANDROID_SDK}/emulator/emulator binary and placing a script like this:

#!/bin/bash
QT_SCREEN_SCALE_FACTORS=1 {FULL_path_to_sdk_here}/emulator/emulator.trick "$@"

This worked great for me, and I have not noticed any drawback. To my surprise the emulator didn't show up really tiny, instead it now fills the whole size of the original window!

This was an issue with screen scaling.

I use KDE plasma with a screen scalling setting of 1.5 which caused this issue.
