Items in explorer not changing color when selected in Windows 10
Solution 1:
Do you happen to have a second monitor with different scaling? Switching between the two as primary displays seems to cause this.
Toggling High Contrast mode on and off seems to fix the issue temporarily so I don't need to reboot. A permanent fix is still required, but I hope this helps in the interim.
Edit: it's possible also that changing theme colours also fixes the issue but I have not tried this yet; I'm waiting for it to break again.
Solution 2:
This problem seems to be occurring only after starting the system from sleep/ hibernate. Instead of restarting every time it occurs, you can rather Restart the Windows Explorer through the task manager.
Simple Fix: Restart Windows Explorer
Solution 3:
I haven't got enough information to give a definite solution, but here are some things you can try to narrow down the possibilites or try to solve it
First thing I would try is to see if the problem is fixed when explorer restarts. Next time you get this issue, open task manager, go to more details and look under processes. Select Windows Explorer from the list and click Restart in the bottom right. See if the issue persists
It could be a problem with your graphics driver - try downloading the latest one from your manufacturer's website (but don't try installing one for a older version of windows as this could make the problem worse)
Another possibility is that some system files are corrupted. Have a look at this article to see how to run sfc
to check your system files.
Does anything else happen at the same time as this (e.g. some stuttering or a black screen?) Check your event viewer and see if there are any errors happening at the same time as you get this bug.
Solution 4:
I have a laptop. When docked, I do not see or use the laptop LCD. Instead, I use 2 external monitors. The monitors were defaulted to 100% scaling. When the laptop lid is closed the scaling for it does not show up on the display settings, but it was 125%. Even though the monitor was not active, its scaling affected the File Explorer highlighting.
