Created attachment 140041 [details] .png screenshot to illustrate the problem On my Dell Latitude 5285 windows machine (Intel HD Graphics 620), when using OpenGL on LO 6.0.1 (which is the default behavior), there are many display problems (see attached screenshot): missing menu bar, missing status bar, blurry fonts, etc. Moreover, there is a shift between the position of the pointer and the UI object affected when you click.
Well, the Latitude 5285 sports a 12.3" display, so at native 1920x1080 resolution you are at ~180ppi, making this a HiDPI issue. But also have issue with the OpenGL drivers for the Intel HD 6xx GPUs as in bug 107764 clip and post result of msinfo32.exe System -> Component -> Display panel, so we can see the Intel driver. And, then update to the current Intel graphics driver and retest, either Dell system specific [1], or Intel's "generic" [2] driver. If that resolves the OpenGL clipping this resolves dupe of bug 107764 =-ref-= [1] Dell's 4836 driver build http://www.dell.com/support/home/us/en/19/drivers/driversdetails?driverId=PDMY7 [2] Intel "generic" driver 4944 build (on laptop systems, the installer may balk) https://downloadcenter.intel.com/download/27484/Graphics-Intel-Graphics-Driver-for-Windows-15-65-?product=128199 [3] Intel instructions to install "generic" driver https://www.intel.com/content/www/us/en/support/articles/000005629/graphics-drivers.html
Thanks for the tip! Indeed, upgrading the video driver solved this issue. Still, I find that the LO UI is quite slow with OpenGL (but that is another issue). The output of msinfo32.exe is below (after upgrading the video driver): Nom Intel(R) HD Graphics 620 ID de périphérique Plug-and-Play PCI\VEN_8086&DEV_5916&SUBSYS_07A41028&REV_02\3&11583659&0&10 Type de carte Intel(R) HD Graphics Family, compatible Intel Corporation Description de la carte Intel(R) HD Graphics 620 Mémoire vive sur la carte 1,00 Go (1 073 741 824 octets) Pilotes installés C:\Windows\System32\DriverStore\FileRepository\ki125882.inf_amd64_507c06df97b349dc\igdumdim64.dll,C:\Windows\System32\DriverStore\FileRepository\ki125882.inf_amd64_507c06df97b349dc\igd10iumd64.dll,C:\Windows\System32\DriverStore\FileRepository\ki125882.inf_amd64_507c06df97b349dc\igd10iumd64.dll,C:\Windows\System32\DriverStore\FileRepository\ki125882.inf_amd64_507c06df97b349dc\igd12umd64.dll Version du pilote 22.20.16.4836 Fichier INF oem19.inf (section iKBLD_w10_DS_GTC) Plans de couleurs Non disponible Entrées de table des couleurs 4294967296 Résolution 1920 x 1280 x 60 hertz Bits/pixel 32 Adresse mémoire 0xD0000000-0xD0FFFFFF Adresse mémoire 0xC0000000-0xCFFFFFFF Port d’E/S 0x0000F000-0x0000F03F Canal IRQ IRQ 4294967285 Port d’E/S 0x000003B0-0x000003BB Port d’E/S 0x000003C0-0x000003DF Adresse mémoire 0xA0000-0xBFFFF Pilote c:\windows\system32\driverstore\filerepository\ki125882.inf_amd64_507c06df97b349dc\igdkmd64.sys (22.20.16.4836, 12,80 Mo (13 422 528 octets), 19/12/2017 23:35)
