TSC frequency mismatch between VM and host

Issue

Recently getting this error in Android Studio 3.5, always four times when starting an emulator:

4:31 PM Emulator: qemu-system-x86_64: warning: TSC frequency mismatch between VM (3398030 kHz) and host (3398029 kHz), and TSC scaling unavailable

ANDROID_EMULATOR_USE_SYSTEM_LIBS=1 was already set - and with ANDROID_EMULATOR_USE_SYSTEM_LIBS=0 it does not start at all.

What to do about it?

Solution

Switching ANDROID_EMULATOR_USE_SYSTEM_LIBS=1/0 once forth and back apparently cleared the user image of the emulator (killall qemu-system-x86_64 was required) and now that annoying error message is gone. The cause might have been recently updating the emulator's system image.
