Description
I've had these rendering glitches (wrong rendering of the xfce start menu icon and wrong scaling of some Qt 5 apps, see attached screenshots) for years on an AMD Athlon 64 X2 + Radeon HD 6670 PC. I have two other newer AMD CPU+GPU PCs that don't have this problem. I have no special system wide config on any of my machines and I've tried a fresh config with another user account. So I'm thinking this must be a GPU rendering issue. On the affected system there is also a motherboard integrated radeon which I disabled in the BIOS.
The strange thing is that KeepassXC used to have this scaling problem, but it no longer has. The scaling problem never disappeared with qTox however.
