[Bug 1518597] Re: All system menus, as well as dolphin and other apps totally unreadable because of overlap
OK, major progress in isolating this issue, at least the root cause. Culprit is java and the fact that it now creates thousands of shared memory segments, for some reason (I am not running any java app I have not been running for months or years but I did rebuild one using the latest jdk). The messed up display issue arises when all shmem segments are busy. All of them have a zero key, some of them claim to have 1 and other 2 processes attached. Most but not all of them have the same size: $ ipcs -m ... 0x 86018571 chrisb 60042864 1 dest 0x 86051340 chrisb 60091200 1 dest 0x 86084109 chrisb 60091200 1 dest 0x 86149646 chrisb 60042864 1 dest 0x 86182415 chrisb 60042864 1 dest 0x 86215184 chrisb 600236400 1 dest ... 0x 135040993 chrisb 60016900761 dest 0x 135073762 chrisb 60016900761 dest 0x 135106531 chrisb 60016900761 dest 0x 135139300 chrisb 60016900761 dest 0x 135172069 chrisb 60016900761 dest 0x 135204838 chrisb 60016900761 dest 0x 135237607 chrisb 60016900761 dest 0x 135270376 chrisb 60016900761 dest 0x 135303145 chrisb 60016900761 dest 0x 135335914 chrisb 60016900761 dest 0x 135368683 chrisb 60016900761 dest 0x 135401452 chrisb 60016900761 dest 0x 135434221 chrisb 60016900761 dest 0x 135466990 chrisb 60016900761 dest 0x 135499759 chrisb 60016900761 dest 0x 135532528 chrisb 60016900761 dest 0x 135565297 chrisb 60016900761 dest 0x 135598066 chrisb 60016900761 dest 0x 135630835 chrisb 60016900761 dest 0x 135663604 chrisb 60016900761 dest 0x 135696373 chrisb 60016900761 dest 0x 135729142 chrisb 60016900761 dest 0x 135761911 chrisb 60016900761 dest 0x 135794680 chrisb 60016900761 dest 0x 135827449 chrisb 60016900761 dest 0x 135860218 chrisb 60016900761 dest 0x 135892987 chrisb 60016900761 dest 0x 135925756 chrisb 60016900761 dest 0x 135958525 chrisb 60016900761 dest 0x 135991294 chrisb 60016900761 dest 0x 136024063 chrisb 60016900761 dest ... $ ipcs -ml -- Shared Memory Limits max number of segments = 4096 max seg size (kbytes) = 32768 max total shared memory (kbytes) = 8388608 min seg size (bytes) = 1 When 'ipcs -m | wc -l' shows 4100 lines, the display messes up.

Re: [Bug 1518597] Re: All system menus, as well as dolphin and other apps totally unreadable because of overlap
OK. Just FYI, I was on 14.XX ever since it came out. When 15.XX came out, April, IIRC, I upgraded but I didn't like it and I went back to 14.XX. These problems just started to happen a couple of weeks ago. I had not had any issues like this previously.
