gl-117 3D game runs with a good FPS. But when I place mouse over a text inscription in the game menu, it lags VERY much.

Would you be able to test using https://cgit.freedesktop.org/drm-tip and send dmesg with drm.debug=0x1 log_buf_len=4M from boot to issue happening. Not sure if this could be even Mesa issue?
I do not want to run experimental kernel software on my production PC.
Can you try then 4.17 upstream kernel and send debug logs? And what is Mesa version you are using? Can you also update that?
How to try try then 4.17 upstream kernel on Ubuntu 18.04 without damaging the system? Could you refer me to a detailed guide? It seems I have the following mesa: $ apt show libegl-mesa0 Package: libegl-mesa0 Version: 18.0.0~rc5-1ubuntu1 How can I update it without damaging my system?
Sadly for this bug report, I exchange disks of two computers, what makes me unable to test it any further. While I have not yet pulled out the disks, I can give this information: Handle 0x0002, DMI type 2, 15 bytes Base Board Information Manufacturer: Acer Product Name: Veriton M4610G Version: Serial Number: Asset Tag: To be filled by O.E.M. Features: Board is a hosting board Board is replaceable Location In Chassis: To be filled by O.E.M. Chassis Handle: 0x0003 Type: Motherboard Contained Object Handles: 0
With this information it is hard to debug further. I will mark this is not fixed.
