Blue flashes with f.lux on Ubuntu 18.04 with amdgpu driver

  • P

    I installed f.lux on Ubuntu 18.04 LTS by using the PPA. It mostly works well, however from time to time the night mode is disabled for a fraction of a second, causing a (relatively bluish) flash of non-modified display. This unexpected flash is stimulating and may partly or completely negate the night dimming effects of f.lux. The video card uses the Xorg amdgpu driver for the AMDGPU(0): Chipset: "AMD Radeon (TM) RX 460 Graphics" (ChipID = 0x67ef). I have dual monitors and the flashes appear independently at different random times on each monitor. Is this a known problem and is there any setting that can be changed to avoid it?
